Recombinant Aprotinin

Catalog Number: RTI16—S

CAS: 9087-70-1

Synonyms: Trypsin Inhibitor

Source: Recombinant aprotinin is a genetically engineered protein expressed in E.coli

Protein Sequence:The amino acid sequence of recombinant aprotinin is identical to bovine lung derived aprotinin

 

1.DESCRIPTION

Aprotinin is a competitive serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Aprotinin forms stable complexes with and blocks the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes and dissociating at pH <3.0. Effective concentration is equimolar with protease. YaxinBio recombinant aprotinin is a genetically engineered protein expressed in E.coli and purified by multi-column.The amino acid sequence of recombinant trypsin is identical to bovine lung derived aprotinin,with equivalent properties compared to native aprotinin and can replace native trypsin for using in a variety of biotechnological processes.

 

2.MAIN FEATURES

Source	Recombinant E. coli
Appearance	Clear, colorless to yellowish liquid
Protein Concentrate	≥ 5.0
Specific Activity (EPU /mg protein)	≥ 3.0
Absorbance (277nm)	≤ 0.8(3 EPU/ml in water)

UNIT DEFINITION:One trypsin inhibitor unit (EPU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmol of N-benzoyl-L-arginineethyl ether(BAEE) per sec at pH 7.6 at 25 °C.

A conversion factor for Aprotinin is: 1 EPU= 1 USP Aprotinin Unit

 

3.RECOMMEND USAGE

Effective concentration is equimolar with protease. The recommend binding is pH＞6.0 and it will dissociate at pH <3.0.

 

4.STABILITY OF STORAGE AND TRANSPORT

Stability of storage: Recombinant aprotinin liquid should be stored under -20℃ in sealed container.It is stable within 6 months at 2-8℃.It is no activity loss after 6 times repeated freezing and thawing.

Stability of transport: The product is stable by blue ice insulation transport.

 

5.PRODUCT ADVANTAGE

a. Animal origin free: Recombinant aprotinin is no exogenous virus contamination,and any animal origin material is not used in the production process.

b. Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.

c. High purity: Higher specific activity.Host protein residues is less than the limits of biological products.

d. Compliance with regulatory requirements: Production equipment and production environment comply with relevant regulatory requirements, and the production process is in full compliance with NSF ISO 9001: 2008 quality system and GMP guidelines.

e. Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.

 

6.PRODUCT USAGE
