Trypsin, Bovine Pancreas
基本信息
| Enzyme Commission (EC) Number【酶学委员会(EC)编号】 | 3.4.21.4 ( BRENDA | IUBMB ) |
| General description【一般描述】 | Native trypsin from bovine pancreas. Serine protease that specifically hydrolyzes amides, peptides, and proteins at the C-terminus side of arginine and lysine residues. Inhibitors include aprotinin, DFP, and soybean trypsin inhibitor. Has an optimal pH of 8.5-8.8. Note: 1 NF unit = 1 USP unit = 3 SU at 30°C, pH 7.6; 1 TAME unit = 19.2 USP units = 57.5 BAEE units; 1 MU = 1,000,000 units. Native trypsin from bovine pancreas. Serine protease that specifically hydrolyzes amides, peptides and proteins at the C-terminal side of arginine and lysine residues. Inhibitors include aprotinin, DFP, and soybean trypsin inhibitor. Note: 1 MU = 1,000,000 units. |
| Warning【警告】 | Toxicity: Irritant (B) |
| Unit Definition【单位定义】 | One USP unit is defined as the amount of enzyme that will digest BAEE and cause an increase in absorbance of 0.003 units at 253 nm per min at 25°C, pH 7.6. |
| Physical form【外形】 | Salt-free |
| Reconstitution【重悬】 | Following reconstitution in HCl, aliquot and freeze (-20°C) for long-term storage or refrigerate (4°C) for short-term storage. Dilute into aqueous buffers (at neutral pH) just prior to use. Following reconstitution in H₂O or buffer, use immediately or aliquot and freeze (-70°C) to minimize autolysis. HCl stock solutions are stable for up to 1 week at 4°C or for up to 1 month at -20°C. H₂O or buffer stock solutions are stable for up to 1 month at -70°C. |
