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.

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.

Preparation Note

Stabilizers: Ca²⁺ in mM concentration rangeInhibitors: TLCK, DFP, PMSF, leupeptin, soybean trypsin inhibitor, trypsin inhibitor from hen egg, aprotinin, α₂-macroglobulin, α₁-antitrypsin, APMSF, and antipain.Storage conditions (working solution): -15 to -25°CThe reconstituted solution is stable for 1 month at -15 to -25°C. Avoid repeated freezing/thawing!

Reconstitution

Following reconstitution in 10 mM HCl, Trypsin, recombinant, proteomics grade is stable at -15 to -25 °C for up to one month. After first reconstitution the product must be stored in appropriate aliquots to avoid repeated freezing and thawing.

Specificity

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.
