Trypsin recombinant, Proteomics Grade

Description

• 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.
• 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.
• 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.[1][2]
• 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.
• Other Notes: For life science research only. Not for use in diagnostic procedures.
