Trypsin

Serine endopeptidases are a class of proteases that use an active-site serine residue as the nucleophile to hydrolyze peptide bonds within proteins or polypeptides. Their members participate in protein digestion, coagulation and fibrinolysis, complement activation, inflammatory regulation, ...

Trypsin (EC 3.4.21.4) is a serine endopeptidase that specifically hydrolyzes peptide bonds at the carboxyl side of lysine (Lys) or arginine (Arg) residues. As biopharmaceuticals such as vaccines, recombinant proteins, and cell therapy products demand higher safety and consistency, the use of ...

Cryopreservation is a method of preserving cells at low temperatures in order to maintain cell activity and function for a long period of time. This method is of great significance for the long-term preservation of cell lines, experimental repeatability, the establishment of gene banks, and the ...

Cell counting with a hemocytometer is a cornerstone of in vitro and in vivo experiments. It improves the precision and reproducibility of your research and increases the reliability of your results.

Procedure for early detection of apoptosis using Annexin V-FITC staining and optional propidium iodide ( PI ) .

Current research has identified a variety of protein hydrolases that can be used to dissociate cells, the most commonly used of which is trypsin, a member of the serine protease family. In the pancreas the precursor of trypsin is synthesised by trypsinogen and secreted as a component of the ...
