About this item
SG-Arginine-C™ endopeptidase (Clostripain, from C. histolyticum) specifically hydrolyzes the carboxy peptide bond of Arginine. SG-Arginine-C™ has been modified chemically by a propriety process to render the enzyme resistant to autolysis and stabilize enzymatic activity. In addition, as a sulfhydryl enzyme, SG-Arginine-C™ is susceptible to inactivation by oxidation and as a result requires reducing agents for protection. The enzyme also requires calcium ion for maximal activity. A special reconstitution buffer is supplied, which contains reducing agents and activators to maintain enzyme activity.
SG-Arginine-C™ is a modified Arginine-C with high specificity, free from other known endopeptidases, that is resistant to autolysis and degradation. SG-Chymotrypsin™ is used for the digestion of proteins for sequence analysis and is suitable for sequencing applications. Use of SG-Arginine-C™ produces consistent activity levels from lot to lot for reproducible digestions.
SG-Arginine-C™ is supplied lyophilized in an activated form in 5μg vials and can be reconstituted to a concentration of 0.25μg/mL by addition of 20μL per vial of the supplied reaction buffer. For fragmentation the enzyme is added to the sample protein in a ratio of 1:100 to 1:20 (enzyme to protein, by weight).
