Highly Specific and Autoproteolytically Resistant Trypsin for Accurate Protein Mass Spec Analysis

Part # PS415

Abstract

We have developed new trypsin that addresses shortcomings of existing Proteomics and MS grade trypsins.

  • The new trypsin is free of non-specific cleavage activity commonly found in Proteomics and MS-grade trypsins.
  • Using a new chemical modification method, we significantly improved autoproteolytic resistance compared to existing Proteomics and MS grade trypsins.
  • Proteolytic efficiency was increased. The new trypsin can be used to effectively digest proteolytically resistant sites.
  • Due to extensive purification, the new trypsin shows superior purity. It is also free of contaminating proteins of animal origin.
