Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. The use of the word cloning refers to the fact that the method involves the replication of one molecule to produce a population of cells with identical DNA molecules. Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA. Molecular cloning methods are central to many contemporary areas of modern biology and medicine. In a conventional molecular cloning experiment, the DNA to be cloned is obtained from an organism of interest, then treated with enzymes in the test tube to generate smaller DNA fragments. Subsequently, these fragments are then combined with vector DNA to generate recombinant DNA molecules. The recombinant DNA is then introduced into a host ...
The genome information is offering opportunities to manipulate genes, polygenic characters and multiple traits in plants. Although a number of approaches have been developed to manipulate traits in plants, technical hurdles make the process difficult. Gene cloning vectors that facilitate the fusion, overexpression or down regulation of genes in plant cells are being used with various degree of success. In this study, we modified gateway MultiSite cloning vectors and developed a hybrid cloning strategy which combines advantages of both traditional cloning and gateway recombination cloning. We developed Gateway entry (pGATE) vectors containing attL sites flanking multiple cloning sites and plant expression vector (pKM12GW) with specific recombination sites carrying different plant and bacterial selection markers. We constructed a plant expression vector carrying a reporter gene (GUS), two Bt cry genes in a predetermined pattern by a single round of LR recombination reaction after restriction ...
For positive-selection cloning of PCR products through blunt-end ligation. Allows direct cloning of PCR products without purification.. GenHunters PCR-TRAP® Cloning System is the most efficient method for cloning PCR products by blunt-end ligation. This system uses a third generation cloning vector that features positive selection for cloning PCR products (see figures next page). Only recombinant plasmids confer antibiotic resistance, making PCR-TRAP® extremely efficient. There is no need for any post-PCR manipulation before cloning, since a significant fraction of PCR products do not contain the 3 overhanging A (Clark, 1988, Nucleic Acids Res. 16:9677 ...

For every Herceptin, for every Enbrel, Humira and Rituxan, and for every successful biotherapeutic product in the market today, there is a long history of its product development. We all hope that our target protein product will make a difference in both the therapeutic market and the lives it will eventually affect as it reaches its ultimate goal of becoming a human therapeutic. The reality is, in order for it to be a feasible therapeutic, the protein must first be manufactured. And one of the very first steps in determining the manufacturing capability of the product is the crucial step of choosing the production cell line that will produce this protein.. There are many challenges in single cell CHO cloning procedures to obtain valuable stable CHO production cell lines. We often rely on efficient cloning strategies and cloning media to execute such a crucial task in the developmental process of a recombinant protein product. An important aspect of cloning strategies is the cloning media ...

The biosynthesis of steroid hormones is an integral component of insect growth, development and reproduction. Although there is an abundance of biochemical data implicating both microsomal and mitochondrial cytochrome P450s in steroid metabolism, molecular genetic information on mitochondrial P450s is almost entirely limited to vertebrate sequences. In the current study, a degenerate polymerase chain reaction (PCR) primer was targeted to the highly conserved region of P450 genes that encodes the heme-binding decapeptide. Using a 5 rapid amplification of cDNA ends (RACE) approach, seven novel cytochrome P450 genes were isolated from Drosophila acanthoptera, including one sequence (CYP12B1) with high regional homology to vertebrate mitochondrial P450s. Sequence analysis of the conceptual translation of the full length gene, obtained by 5RACE, revealed an amphipathic NH2-terminus rich in basic and hydrophilic amino acids, a characteristic feature of mitochondrial P450s that distinguishes them ...
During the last few decades, techniques for manipulating eukaryotic as well as prokaryotic DNA have witnessed a remarkable development. There are three main phases of the development of these techniques, which include recombinant DNA technology and gene cloning; polymerase chain reaction and DNA chips and microarrays. Using recombinant DNA technology, we can isolate and clone single copy of a gene or a DNA segment into an indefinite number of copies, all identical. This became possible, because bacteria, phages and plasmids reproduce in their usual style, even after insertion of foreign DNA, so that the inserted DNA also replicates faithfully with the parent DNA. This technique is called gene cloning. It involves the production of a large number of identical DNA molecules from a single ancestral DNA molecule. The essential characteristic of gene cloning is that the desired gene or DNA fragments must be selectively amplified resulting in a large increase in copy number of selected DNA sequences. ...

P-57. Generating and Sequencing Full-length cDNAs of Novel Human Genes Within the German cDNA Consortium. Ruth E. Wellenreuther, Stefan Wiemann, Daniela Heiss, Nina Claudino, Annemarie Poustka, Department of Molecular Genome Analysis, German Cancer Research Center, Im Neuenheimer Heidelberg, GERMANY. We generate human cDNA libraries that are enriched in full length clones i.e. from the translation start to the poly A tail. These libraries are used for a) systematic sequencing within the cDNA consortium of the Genome Project aiming at the identification and analysis of as many new genes as possible and b) for screening to isolate full length clones of partial genes. Libraries are created by directional cloning of cDNAs into plasmid vectors. Full-length enrichment is achieved via Clontechs SMART technology. This method is PCR-based, and in our modified strategy, we amplify and clone selective size windows of the cDNA fraction above 3 kb.Clones from the libraries generated within this project are ...
The complete nucleotide and amino acid sequence of GP-2 was determined initially by molecular cloning technique from peptide sequence for rat, dog and humans (12, 13, 18, 43). The cDNA encodes a protein of 530 aa in humans with 67% identity to rat and 72% to dog GP-2. The primary sequence encodes 10 (human) or 8 (dog) Asn-linked glycosylation sites. This is consistent with data for in vitro translation by reticulocyte lysate that yields a protein of 55 kDa and treatment with N-glycanase which reduces the molecular mass of canine GP-2 from 75 kDa to 52 kDa (12, 18). Rat GP-2 has been shown to possess 5 or 6 N-linked high mannose carbohydrate chains (16). The primary protein sequence is also post-translationally glycosylated on its carboxyl terminal to a GPI moiety in the membrane during passage through the Golgi to reach the ZG (11, 13, 17). This GPI moiety contains a phosphoethanolamine linker attached to the protein, a 4-5 sugar core and a phosphatidylinositol whose hydrocarbon chains insert ...
Andre SzyszkowskiPsy 13004/28/05 Cloning: Choice is Ethical Thousands of people a year are placed on the organ donors list. Thousands of people a year are diagnosed with diseases that are dubbed fatal unless a transplant or transfusion is given. This has created a large demand for some alternative method to the present donor practice. Research in the taboos cience of cloning seems to provide a viable method in which to aid the problem aforementioned and many others as well. But is it ethical? Cloning technology is expected to aid the result in several medical breakthroughs. It is thought that there may one day be a cure for cancer. This is because the cloning process helps us understand the process of cell differentiation. Theories exist that if a cure for cancer can be found, then further testing may lead to a cure for heart attacks and cloning organs for organ transplantation. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and ...
44.38935 -68.20742 BAR HARBOR, Maine - New scientific evidence has heightened concerns about the safety of cloning human beings, an international authority warned yesterday.. "We now believe that the potential to make a normal human baby with cloning is almost zero," said Dr. Rudolf Jaenisch, professor of biology at the Massachusetts Institute of Technology, at a genetics conference at Maines Jackson Laboratory.. "Cloning a normal human is an illusion. There are major problems, and the problems are very serious.". Dr. Jaenisch, who helped pioneer gene transfer and cloning, said the public continues to be enthralled by stories of maverick doctors who supposedly plan to clone human beings.. Italian doctors in Rome, for instance, claim that they will clone a baby by next spring, with $500,000 provided by a couple whose infant died after heart surgery. An American firm called Clonaid has made repeated claims about a imminent human cloning.. "Cloning a normal baby is utter nonsense," said Dr. ...
Introduction. Does cloning benefit or endanger society? Marley Gibbons-Balfour Case Study: Biology Contents Introduction 1 Background Science 2 Arguments against 4 Arguments for 7 Summary 10 Conclusion 11 Bibliography 12 Introduction Cloning has quickly become one of the most contentious issues in modern society, along with other issues like abortion, homosexuality and euthanasia. Due to the conflicted teachings and ideologies of many people in the world, there is no general consensus about cloning. Some people feel that it could benefit humans (through cures, through solving infertility and through knowledge), while others feel it could endanger humans and is a bad thing (due to ethical issues and due to being unaware of what could happen if it didnt work). Because of this, I have decided to investigate whether cloning actually does benefit or endanger society. I will go about this by collecting 6 sources (3 against cloning and 3 for cloning) and evaluating the evidence they present with the ...
The cloning of a novel murine gene that encodes a protein with lymphopoietic activity is described. The activity was initially identified in a coculture system of an adherent thymic stromal cell line with a medullary phenotype, Z210R.1, and day 15 fetal liver (6). Interestingly, the nonadherent lymphoid-like cells that grew in these cocultures phenotypically resembled B cells. A clonal lymphoid line (NAG8/7) was derived from long term cocultures, and this line expresses B220, 6C3 (BP-1), and is surface μ+, but κ chain negative. Importantly, NAG8/7 cells proliferated in response to conditioned medium from the Z210R.1 cell line and thus became the basis of a bioassay that allowed for the preliminary characterization of the growth factor and the eventual cloning of the cDNA encoding this activity.. The cDNA encoding the NAG8/7 growth activity was cloned from a library made from the Z210R.1 cell line. Based on the nucleotide sequence, the mature TSLP protein consists of 121 amino acids with 3 ...

Introduction. Science and cloning. Why are researchers and scientists so interested in cloning? The main view on cloning is that it is morally wrong and it is interfering with the very thing that has made life possible, although the reasons behind wanting to clone such large animals as sheep is not just to make a copy. Scientists claim that cloning an animal would be directly connected to there work aimed at producing medicines in the milk of animals. Researchers have actually managed to transfer human genes that produce useful proteins into large animals like sheep and cows, so that they also produce these useful proteins. Scientists claim that if an animal has these human genes then they can treat conditions like hemophilia and cystic fibrosis as well as other lung conditions. ...read more. Middle. Dolly the sheep.

Almost seven years after the birth of Dolly the sheep, cloning has shown mixed progress. Scientists have achieved it in more than a dozen mammal species, but an efficient cloning process still eludes them.
Professor Zavos and his supporters of cloning feel that with the careful continuation of research, the technological benefits of cloning clearly outweigh the possible social consequences. In their minds, final products of cloning, like farm animals and laboratory mice will not be the most important achievement. The applications of cloning they envision are not nightmarish and inhumane, but will improve the overall quality of science and life. Cloning will help to produce discoveries that will affect the study of genetics, cell development, human growth, and obstetrics. Human cloning is not the issue; it is merely a threat to the continuation of cloning research. From the reproductive point of view, in in-vitro fertilization (IVF), a doctor often implants many fertilized ova (embryos) into a womans uterus and counts on one resulting in pregnancy. However, some women can only supply one egg. Through cloning, one can increase the number of the embryos at transfer and that could increase ...

Gurdon began cloning experiments using nonembryonic cells-specifically, cells from the intestinal lining of tadpoles. Gurdon believed that the tadpoles were old enough so that cells taken from them would be differentiated. Gurdon exposed a frog egg to ultraviolet light, which destroyed its nucleus. He then removed the nucleus from the tadpole intestinal cell and implanted it in the enucleated egg. The egg grew into a tadpole that was genetically identical to the DNA-donating tadpole. But the tadpoles cloned in Gurdons early experiments never survived to adulthood and scientists now believe that many of the cells used in these experiments may not have been differentiated cells after all. In later work, however, Gurdon successfully produced sexually mature adult frogs from eggs into which genetically marked nuclei had been transplanted from differentiated tadpole cells ...

is it possible to optimize a transfected cell-line (by G418-selection) by subcloning, i. e. to get a better receptor expession. I think if i got a monoclonal mammalial cell-line which is overexpressing a receptor gene, it could improve the expression of this gene, to make a subcloning by dilution. I think the cells are dividing over the time and are so not longer be monoclonal ...
Cloning of DNA sequences DNA Sequence for cloning may be obtained by two ways: using mRNA and Separation of DNA sequence from the genome of the cell, where the cells are broken up and ...
A colony stimulating factor. CSF-1, is a lymphokine useful in overcoming the immunosuppression induced by chemotherapy or resulting from other causes. CSF-1 is obtained in usable amounts by recombinant methods, including cloning and expression of the murine and human DNA sequences encoding this protein.
Cloning can be a very sensitive subject. It seems that its a battle between science and ethics. Does the ladder outweigh the former or vice versa? Maybe a few definitions will shed some light on the subject. Cloning is to create a genetic duplicate of...

I think this depends on what youre cloning. My inserts tend to be ,150 bp, which means getting 3 ug of product requires significantly larger PCR volumes. Smaller inserts are also more difficult to purify without loss downstream, hence the large volume that I generally use. -- ...
