General description

Trypsin is a serine protease that is usually used in biochemistry and biology as an important enzymatic reagent. This method produces a highly purified trypsin product suitable for proteomics research. Proteomics Grade ideal for use in both solution and in-gel tryptic digestions. Trypsin, a serine protease, is present in the digestive system of several vertebrates.

Application

Trypsin from porcine pancreas is used for the following applications:
  • In-gel protein digestion and MALDI-TOF mass spectrometry analysis
  • Electrospray Ionization Mass Spectrometry (ESI-MS) analysis
  • Surface proteome profiling of L. plantarum
  • Gel Filtration, Ultracentrifugation, and Rotary Shadowing Electron Microscopy
  • Mass spectrometry

Biochem/physiol Actions

Trypsin is routinely 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.. The enzyme also exhibits esterase and amidase activities. Trypsin acts as a cell culture tool. It is used to hydrolyze allergenic proteins to produce hypoallergenic milk in industries.

Evaluation of Recombinant, Chemically Treated Trypsin in Proteomics and Protein Characterization Assays

Validation of RNAi Knockdown Using Multiple Reaction Monitoring and Protein-AQUA

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.

Procedure for Enzymatic Assay of Trypsin (EC 3.4.21.4)

This procedure is for products with a specification for Trypsin activity using Na-Benzoyl-L-arginine ethyl ester (BAEE) as a substrate. The procedure is a continuous spectrophotometric rate determination (A253, Light path = 1 cm).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
