产品属性:
BioUltra, recombinant, expressed in Nicotiana, >5 TIU/mg protein Synonym : Trypsin inhibitor (basic) Molecular Formula : C284H432N84O79S7 Molecular Weight : 6511.44 CAS Number 9087-70-1 蛋白酶抑制剂 Aprotinin from bovine lung Descriptions Preparation Note Contains no animal-derived components or impurities, and is manufactured by transient expression of the aprotinin message in RNA (+)-strand tobacco mosaic virus vectors propagated in non-transgenic Nicotiana plants. Unit Definition One trypsin inhibitor unit (TIU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmole of N-α-benzoyl-DL-arginine p-nitroanilide (BAPNA) per min at pH 7.8 at 25 °C. Biochem/physiol Actions Serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Effective concentration equimolar with protease. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or <3. Properties recombinant expressed in Nicotiana grade BioUltra assay ……………………………………………………………………… ≥ 98% (SDS-PAGE) mol wt …………………………………………………………………….mol wt ~ 6,500 Gene Information cow ................................................
