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.||Appearance: |Off-white, homogeneous, free flowing powder||Solubility: |Light yellow, clear, complete||pH: |As Reported||Manufactured using Trypsin 1:250 (Porcine), Cat# T8670:|Source: Porcine pancreas|Trypsin: ≥ 250u/mg|Chymotrypsin: ≥ 40u/mg|Endotoxin (LAL): ≤ 10Eu/ml|Porcine Parvovirus (Hemagglutination, PCR): None Detected|E. coli: None Detected||Unit Definition:|Trypsin: The amount of enzyme which causes an increase in absorbance at 253nm of 0.003 per minute at 25°C
