Application
Trypsin recombinant, Proteomics Grade, is used to specifically digest proteins separated by 2D gel electrophoresis or liquid chromatographic methods during sample preparation for mass spectrometry.
Biochem/physiol Actions
Serine endopeptidase, hydrolyzing specifically proteins and peptides at the carboxy side of the basic amino acids Arg and Lys. Amide and ester bonds of Arg and Lys are also cleaved.
General description
This trypsin preparation is generated from the recombinant Pichia pastoris strain and is, thus, free of chymotrypsin. Trypsin recombinant, Proteomics Grade, exhibits high specific activity.
Other Notes
For life science research only. Not for use in diagnostic procedures.
