  • For example, Degussa AG (now Evonik AG) reported a LeuDH and FDH coupling system to perform repeated batch reactions with an enzyme membrane reactor on a ton scale and the space-time yield of l -tle achieved 638 g/L/day [ 14 ]. (biomedcentral.com)
  • All HF-restriction enzymes come with Gel Loading Dye, Purple (6X) . (neb.com)
  • Every ready-to-use ladder is supplied with the nuclease-free Loading Dye Solution, which ensures optimal migration and quantification of your DNA probes. (biologicals.cz)
  • Using standard BioBrick assembly methods, ligate the integration site onto a low-copy BioBrick plasmid (Fig. 3). (igem.org)
  • The next step is to cut at A1 and the Unique site and ligate this DNA onto the higher copy garbage (with cut sites) plasmid. (igem.org)
  • Chymotrypsin -- An enzyme that catalyses the hydrolysis (the breakdown) of proteins into peptides or amino acids in the small intestine. (nih.gov)
  • A few buffer conditions suit nearly all the restriction enzymes but no single buffer allows activity of every enzyme. (rice.edu)
  • Prior to digesting DNA, purify DNA amplified via PCR to remove primers and to change the buffer. (haverford.edu)
  • The term modifications in genetics refers to both naturally occurring and engineered changes in DNA. (wikipedia.org)
  • DNA stands for deoxyribonucleic Acid . (wikibooks.org)
  • DNA, or deoxyribonucleic acid -- The primary genetic material of all cellular organisms and the DNA viruses. (nih.gov)
  • Are you digesting with multiple restriction enzymes that require different buffers? (haverford.edu)
  • Temperature-sensitive (TS) plasmids were generated through chemical mutagenesis of a derivative of the streptomycin resistance parent plasmid pD70, isolated from Mannheimia hemolytica serotype 1. (usda.gov)
  • In this work, a novel fusion enzyme (GDH-R3-LeuDH) for the efficient biosynthesis of l -tle was constructed by the fusion of LeuDH and GDH mediated with a rigid peptide linker. (biomedcentral.com)
  • These results demonstrated the great potential of the GDH-R3-LeuDH fusion enzyme for the efficient biosynthesis of l -tle. (biomedcentral.com)
  • Then transform the plasmid into the host bacterial strain and expose the bacteria to the phage. (igem.org)
  • Phage integration site flanked by BioBrick restriction enzyme sites and the absent site. (igem.org)
  • Prepare a high copy BioBrick plasmid with the A1 and Unique site by PCRing these sites onto some garbage DNA and cutting/ligating the DNA onto the plasmid. (igem.org)
  • At this stage it is necessary to create restriction enzyme cut sites in the locations needed. (igem.org)
  • For the next step to proceed, it is necessary to modify the source DNA, the BioBrick part, by adding cut sites using PCR. (igem.org)
  • These cut sites should be in on the inside of E, X, S, and P as before (similar to the garbage DNA) and should match the restriction sites that were SDM'ed into the sub host DNA. (igem.org)
  • Prepare a BioBrick plasmid with the A1 and Unique sites on the inside of the normal BioBrick cut sites (Fig. 4). (igem.org)
  • Restriction enzymes can bind to and cut DNA at specific sites. (cshl.edu)
  • They also specify the sites for linking to build RNA along a DNA template. (nih.gov)
  • Double-stranded RNA , on the other hand, has much larger grooves, and therefore, it is more subject to being broken down by enzymes. (wikibooks.org)
  • The connection between the strands of double-stranded DNA is tighter than double-stranded RNA . (wikibooks.org)
  • In other words, it's much easier to unzip double-stranded RNA than it is to unzip double-stranded DNA. (wikibooks.org)
  • Examples of nuclease contamination studies for some of our HF restriction enzymes are shown below. (neb.com)
  • Three TS plasmids which failed to replicate at or above 42°C in M. hemolytica but which were fully functional below 31°C were selected for further analysis. (usda.gov)
  • Herein we have developed a widely applicable method for constructing unmarked mutations in this family of bacteria using a newly engineered temperature-sensitive plasmid, derived from an endogenous plasmid of M. haemolytica pD70. (usda.gov)
