Trypsin MS approved

Trypsin MS approved

Product Description

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'ed by MS◆ Modified by reductive methylation◆ Sourc: Porcine pancreas◆ Premium purity, superior stability◆ Packing size: One vial (100 µg)
