Description

General description

Trypsin is a serine protease that specifically hydrolyzes peptide bonds at the carboxyl side of Lysine and Arginine residues. This modified trypsin has been treated with N-tosyl-L-phenylalanine chloromethyl ketone (TPCK) to inactivate extraneous chymotryptic activity. This trypsin product also contains calcium chloride, which may improve consistency in digestion. Each package contains 10 vials, with 25 μg in each vial. 

Application

Trypsin, TPCK-Treated has been used for the digestion of protein samples to generate peptides for LC-MS (liquid chromatography–mass spectrometry)/MS analysis.

Trypsin, TPCK-Treated has been used in enzymatic treatment to cleave the recombinant native B-cell lymphoma-extra large (Bcl-xL)-ΔTM monomer to generate fibrils (the third type of Bcl-xL fibril, called “BclxLcf37”). It has also been used in influenza infection experiments as a supplement in infection/DMEM serum-free medium to infect A549 cells with influenza A H1N1 virus at a multiplicity of infection (MOI) to perform multi-round infection.
