Enzymes

Enzymes, or biological catalysts, are some of the most widely manipulated reagents in molecular biology and biochemistry research and diagnostics. The appropriate enzymatic reagent depends on the type of enzyme, target molecule, final reaction product, reagent grade, and working volume. Peptidases, enzymes that initiate protein catabolism by hydrolysis of the peptide bonds that link amino acids together in the polypeptide chain, DNA glycosylases, the enzymes involved in base excision repair, and kinases, enzymes that transfers phosphate groups from high-energy donor molecules, such as ATP to specific substrates, are examples of available enzymes from suppliers such as New England Biolabs®, Promega, and Roche. DNA experiments use nucleic acid-specific enzymes, such as restriction enzymes which cut DNA, ligases which join DNA bases, and topoisomerases which uncoil DNA. If a simple protein detection scheme is the target, the available selection of HRP (Horseradish Peroxidase) products will complement any experimental design. Enzymes are synthesized in various quantities, so researchers have the option of 100µg or 100g of Trypsin, for example. Catalyze your research goals with the products in this enzyme collection.
