Trypsin 1:250 (Porcine) (EC 3.4.21.4, Porcine pancreas)

Trypsin is a pancreatic serine protease with substrate specificity based upon positively charged lysine and arginine side chains. Trypsin is inhibited by organophosphorous compounds such as diisopropylfluorophosphate and porcine-derived inhibitors. Used in protein sequencing and tissue disassociation. Trypsin: >250u/mg, Chymotrypsin: <75u/mg, Endotoxin: <10EU/mg, Porcine Parvovirus (Hemagglutination, PCR): None Detected, Ash: <2.5%, Moisture: <5.5%, Microbiological Analysis: , Plate Count:, <1000cfu/g, Yeast/Mold: <10cfu/g, P. aeruginosa: None Detected in 25g, Salmonella: None Detected in 25g, E. coli: None Detected in 25g, S. aureus: <10cfu/g, Unit Definitions: Trypsin: The amount of enzyme which causes an increase in absorbance at 253nm of 0.003 per minute at 25°C, Chymotrypsin: The amount of enzyme which causes an decrease in absorbance at 237nm of 0.0075 per minute at 25°C. Storage and Stability: Powder may be stored at 4°C. Stable for 12 months after receipt at 4°C. Certificate of Origin: USA
