For trypsin digestion of peptides, use a ratio of about 1:100 to 1:20 for trypsin:peptide. The typical use for this product is in removing adherent cells from a culture surface. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the culture. Trypsins have also been used for the re-suspension of cells during cell culture, in proteomics research for digestion of proteins and in various in-gel digestions. Additional applications include assessing crystallization by membrane-based techniques and in a study to determine that protein folding rates and yields can be limited by the presence of kinetic traps.
Trypsin from bovine pancreas has been used for enzymatic digestion of nucleus pulposus (NP) cells during human NP cells isolation. It has also been used as a immunopanning reagent for purification of cells.
Specifications & Purity
BioReagent, for cell culture, essentially salt-free, lyophilized powder,≥9,000 BAEE units/mg protein
Biochemical and Physiological Mechanisms
Trypsin cleaves peptides on the C-terminal side of lysine and arginine residues. The rate of hydrolysis of this reaction is slowed if an acidic residue is on either side of the cleavage site and hydrolysis is stopped if a proline residue is on the carbox
