Additional Information and Online Ordering »

Pierce Trypsin Protease, MS Grade, is a serine protease derived from porcine pancreatic extracts. The enzyme is TPCK-treated to eliminate chymotryptic activity and methylated to improve stability during protein digestion. This mass spectrometry-grade, modified trypsin is then repurified, lyophilized in glass vials and packaged in convenient 5 x 20μg, 5 x 100μg, and 1mg fill sizes.


  • Exceptional selectivity – cleaves at the carboxyl side of lysine and arginine residues with greater than 95% specificity

  • High purity – no detectable chymotrypsin activity

  • Enhanced stability – modified and lyophilized for reduced autolytic activity

  • Economical – available in larger fill sizes that are more cost effective

Recommended for:

  • In-gel digestion of proteins from 1–D or 2–D gels
  • In-solution tryptic digestion of proteins
