Excellent Specificity and Resistance to Autolytic Digestion
Trypsin Gold, Mass Spectrometry Grade, is manufactured to provide maximum specificity. Lysine residues in the porcine trypsin have been modified by reductive methylation, yielding a highly active and stable molecule that is extremely resistant to autolytic digestion. The specificity of the purified trypsin is further improved by TPCK treatment, which inactivates chymotrypsin. The treated trypsin is then purified by affinity chromatography and lyophilized to yield Trypsin Gold, Mass Spectrometry Grade.
Each lot of quality-tested Trypsin Gold, Mass Spectrometry Grade, is qualified for use with in-gel protein digestion and mass spectrometric analysis. For more information, see the Protein Purification and Analysis chapter of the Protocols and Applications Guide.
