High Activity Recombinant Soybean Trypsin Inhibitor ≥1.0 U/mg pro.
1.Product Introduction
Soybean trypsin inhibitor is a serine protease inhibitor, which can inhibit the activity of trypsin, chymotrypsin, and plasmin. The ability to inhibit trypsin is higher than that of chymotrypsin and plasmin. In addition, it can inhibit plasma kallikrein, clotting factor Xa, but can’t inhibit metalloproteinase, tissue kallikreins, acid protease, and sulfur-containing protease. A suitable pH range for inhibiting trypsin is pH 6.0-10.0. Recombinant soybean trypsin inhibitor was expressed by recombinant E.coli and purified without animal-derived contamination and no other protease.
2.Product Features
(1) Protein content: 90% -110% of the indicated amount.
(2) Specific enzyme activity: ≥1.0 U / mg pro.
(3) HPLC purity identification: the main peak purity by area normalization method is not less than 90%.
Inhibitor enzyme activity unit: The ability to inhibit the activity of a trypsin unit is called an inhibitor activity unit (U).
Trypsin unit: One trypsin unit (micro katal) is defined to hydrolyze 1 μmol of N-benzoyl-L-arginine ethyl ester (BAEE) per second.
3.Product Instruction
Inhibitors and protease can be combined in equimolar amounts, the recommended pH for combination is pH>6.0 , inhibitors and protease won’t be combined when pH<5.0.
4.Stability
Stability of storage: Lyophilized powder is stable for 24 months at 2-8℃
Stability of transportation: Blue ice insulation transportation, stable activity.
5.Product Advantage
Animal origin free: The product is produced by recombination and no any animal source material is used in the production process. No exogenous virus contamination, safe to use.
Stable quality: Stable and continuous batch supply, little difference between batches of products, stable quality. Production process follows NSF ISO 9001:2015 quality system and complies with GMP guidelines and provides relevant regulatory support documents.
Complete quality documents: According to customer requirements, relevant regulatory support documents can be provided.
6.Product Usage
Soybean trypsin inhibitor is a serine protease inhibitor. It can form a stable complex with protease to block the active site of the enzyme. Such as: inhibition of serine protease activity in recombinant protein production; cell culture and other biotechnology processes.
