Sequencing Grade Recombinant Trypsin, Mass Spectrometry Grade For Proteomics
Sequencing Grade trypsin
Source:Expressed in E. Coli, methylation modified.
Trypsin specifically hydrolyzes peptide bonds at the carboxyl side of lysine and arginine residues. Recombinant trypsin is free of any other proteases activities, and TPCK is unnecessary and not contained. Unmodified trypsin is subject to auto-proteolysis, generating fragments that can interfere with protein sequencing or HPLC/MS peptides analysis. YaxinBio’s sequencing grade modified trypsin is recombinant porcine trypsin modified by reductive methylation, rendering it resistant to proteolytic digestion.
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.
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.
The amino acid sequence of sequencing grade recombinant trypsin is identical to porcine pancreas-derived trypsin,with equivalent properties compared to native trypsin, and there are many advantages, such as no enzyme activity, high stability, non-self-cutting, high activity.When used, it is no non-specific fragments and self-cutting fragments.Sequencing grade recombinant trypsin can replace native trypsin for using in a variety of biotechnological processes,such as specific protein digestion, protein sequencing, peptide mapping, proteomics studies, Z-D peptides on the peptidase digestion.
