Trypsin MS approved from porcine pancreas

Trypsin MS approved is suitable for digestion of proteins for mass spectrometry analysis. Reductive methylation of the lysine residues of trypsin results in a stable product that is extremely resistant to autolytic degradation. Trypsin MS approved is purified by chromatography. No chymotryptic activity is detectable. Every lot is approved for use in in-gel digestion and mass spectrometry analysis. Specificity verified by digestion of oxidized B-chain of insulin. A Trypsin Peptide (TP) Standard is available separately (cat. no. 37285) allowing internal calibration for enhancing mass accuracy. The TP standard provides tryptic activity to generate masses m/z 842 and 2211.◆ Each lot is QC-tested by MS◆ Modified by reductive methylation◆ Source: Porcine pancreas◆ Premium purity, superior stability
