• Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar. (wikipedia.org)
  • Biomolecules are separated by applying an electric field to move the charged molecules through an agarose matrix, and the biomolecules are separated by size in the agarose gel matrix. (wikipedia.org)
  • Agarose gel is easy to cast, has relatively fewer charged groups, and is particularly suitable for separating DNA of size range most often encountered in laboratories, which accounts for the popularity of its use. (wikipedia.org)
  • Agarose gel is a three-dimensional matrix formed of helical agarose molecules in supercoiled bundles that are aggregated into three-dimensional structures with channels and pores through which biomolecules can pass. (wikipedia.org)
  • The melting temperature is different from the gelling temperature, depending on the sources, agarose gel has a gelling temperature of 35-42 °C and a melting temperature of 85-95 °C. Low-melting and low-gelling agaroses made through chemical modifications are also available. (wikipedia.org)
  • Agarose gel has large pore size and good gel strength, making it suitable as an anticonvection medium for the electrophoresis of DNA and large protein molecules. (wikipedia.org)
  • Agarose gel has lower resolving power than polyacrylamide gel for DNA but has a greater range of separation, and is therefore used for DNA fragments of usually 50-20,000 bp in size. (wikipedia.org)
  • A 0.9% agarose gel has pores large enough for the entry of bacteriophage T4. (wikipedia.org)
  • Low EEO agarose is therefore generally preferred for use in agarose gel electrophoresis of nucleic acids, but high EEO agarose may be used for other purposes. (wikipedia.org)
  • The pore size of a 1% gel has been estimated from 100 nm to 200-500 nm, and its gel strength allows gels as dilute as 0.15% to form a slab for gel electrophoresis. (wikipedia.org)
  • Agarose gels are often used for the separation of large molecules of proteins and DNA due to their large pore size. (ginobiotech.com)
  • Low Melt Agarose (Molecular Biology Grade) -commonly used as a gel matrix when fragment recovery is desired after electrophoresis. (ibisci.com)
  • The melting point of agarose is between 62 and 65°C, and it can be maintained in a liquid state for several hours at 37°C after melting and solidifies into gel at 30°C. It is mostly used for in situ digestion of chromosomal DNA and DNA fragment recovery within the gel. (ginobiotech.com)
  • Electroendosmosis is a reason agarose is used in preference to agar as the agaropectin component in agar contains a significant amount of negatively charged sulphate and carboxyl groups. (wikipedia.org)
  • A number of factors can affect the migration of nucleic acids: the dimension of the gel pores (gel concentration), size of DNA being electrophoresed, the voltage used, the ionic strength of the buffer, and the concentration of intercalating dye such as ethidium bromide if used during electrophoresis. (wikipedia.org)
  • These negatively charged groups create a flow of water in the opposite direction to the movement of DNA in a process called electroendosmosis (EEO), and can therefore retard the movement of DNA and cause blurring of bands. (wikipedia.org)
  • Basic Molecular Biology Agarose -slightly less refined agarose that is ideal for routine electrophoresis procedures. (ibisci.com)
  • This relationship however breaks down with very large DNA fragments, and separation of very large DNA fragments requires the use of pulsed field gel electrophoresis (PFGE), which applies alternating current from different directions and the large DNA fragments are separated as they reorient themselves with the changing field. (wikipedia.org)
  • Agarose is often used in biochemistry laboratories as a semi-solid support in techniques such as electrophoresis and chromatography for the separation and analysis of biological macromolecules or small molecules. (ginobiotech.com)
  • High quality Bac-Agar is void of any inhibitors that can mask optimal development of microorganisms. (ibisci.com)
  • Where are IBI agarose and agar products sourced from? (ibisci.com)
  • IBI Scientific agar and agarose products are derived from the highest quality red algae in the world-har-vested from seaweed beds off the coasts of Southern Europe, North Africa, North America, South America and Oceania. (ibisci.com)
  • When you choose IBI sustainably sourced agar and agarose products, rest assured that the reagent you love will continue to be there for you 3, 5 or more years down the road. (ibisci.com)
  • Bacteriological agar is a mixture of 2 components-the linear polysaccharide agarose and a smaller molecule called agaropectin. (ibisci.com)
  • Agarose is an organic substance with the chemical formula C24H38O19, a white or yellow bead-like gel particle or powder, which is a linear polymorph. (ginobiotech.com)
  • Agarose is a linear polymorph and agaropectin is a heterogeneous mixture of many smaller molecules. (ginobiotech.com)
  • Gino Biotech is a very good agar powder and agarose supplier, they are very professional and patient. (ginobiotech.com)
  • The removal of agaropectin in agarose substantially reduces the EEO, as well as reducing the non-specific adsorption of biomolecules to the gel matrix. (wikipedia.org)
  • Shortages in the agar and agarose industry have historically created challenges for manufacturers to guarantee a dependable product. (ibisci.com)
  • Why is sustainability important in the agar and agarose industry? (ibisci.com)
  • The properties of low melt agarose promote quick and thorough digestion of gel slices during gel extraction allowing a maximum amount of DNA to be recovered from the gel. (ibisci.com)
  • Bacteriological agar is used as a gelling agent in the preparation of culture media for microbiological applications. (ibisci.com)
  • Does not adversely affect other downstream applications - gel extraction, sequencing, etc. (ibisci.com)
  • The lower sulphate content of low EEO agarose, particularly low-melting point (LMP) agarose, is also beneficial in cases where the DNA extracted from gel is to be used for further manipulation as the presence of contaminating sulphates may affect some subsequent procedures, such as ligation and PCR. (wikipedia.org)
  • A greater demand for agar and agarose over the last century has not come without difficulties. (ibisci.com)
  • An excellent low-cost agarose for resolving molecules greater than 1kb in size and more than 15% in size of each other. (ibisci.com)
  • The limit of resolution for standard agarose gel electrophoresis is around 750 kb, but resolution of over 6 Mb is possible with pulsed field gel electrophoresis (PFGE). (wikipedia.org)
  • It uses small, pinhole aperture to eliminate blurring of image and improved resolution. (microrao.com)
