General description

Trypsin is a pancreatic serine endoprotease. SOLu-Trypsin is made from recombinant trypsin, porcine sequence. It does not possess chymotryptic activity.

Application

Poster: Evaluation of Recombinant, Chemically Treated Trypsin in Proteomics and Protein Characterization Assays
SOLu-Trypsin:
  • has been used to digest the gel pieces for mass spectrometry identification of active deubiquitnases (DUBs)
  • has been used in trypsin sensitivity assay
  • may be used for the digestion of wine proteins

Biochem/physiol Actions

Trypsin is used in proteomics research for peptide mapping and protein sequence work due to its highly specific cleavage resulting in a limited number of tryptic peptides. It hydrolyzes peptide bonds specifically at the carboxyl side of arginine and lysine residues.
  • SOLu-Trypsin (EMS0004) is our exclusive, Advanced Proteomics Grade enzyme that is solution-stable for mass spectrometry.
  • Designed to be stable in solution when refrigerated, SOLu-Trypsin can be used immediately without preparation.
  • Other forms of trypsin require thawing or reconstitution, and must be discarded if not used immediately.
  • SOLu-Trypsin allows excess product to be saved for future use, thus eliminating unnecessary waste and cost.
  • It is formulated with a high-purity recombinant trypsin, free of chymotryptic activity, to ensure high fidelity digestion.

Features and Benefits

  • Ready to use - no preparation, such as reconstitution or thawing, is required
  • Fits seamlessly into established workflow - no need to modify protocols
  • Eliminates waste - remains stable in the refrigerator after use so there is no need to discard excess product
  • Recombinant, porcine sequence - no chymotryptic activity
  • Stable for short-term use at room temperature in an autosampler or on a liquid handling robot
