Recombinant Enterokinase

Recombinant Enterokinase
Product Description

DESCRIPTION
YaxinBio Enterokinase is a kind of highly purified recombinant bovine enterokinase light chain. The enzyme has been extensively purified by HPLC and there are no traces of other contaminating proteases. Enterokinase specifically hydrolyzes peptide bond at the carboxyl side of lysine residue preceded by four aspartic acids: Asp-Asp-Asp-Asp-Lys (DDDDK). So, enterokinase can remove N-terminal fusion protein or tags to get aim protein with native amino acids sequence.
PRODUCT ADVANTAGE
Animal origin free: Recombinant enterokinase is no exogenous virus contamination,and any animal origin material is not used in the production process.

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

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

Lyophilized powder: The product is lyophilized powder and is easy to store and transport.
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.

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