VWA2 Human

A domain-containing protein similar to matrilin and collagen, AMACO, Colon cancer secreted protein 2, CCSP-2.

Von Willebrand Factor A Domain Containing 2 (VWA2) is an extracellular matrix protein containing vWA-like domains. VWA2 contains a signal peptide sequence, an N-terminal VWA domain connected to 2 additional tandem vWA domains by a cysteine-rich sequence and an EGF-like domain. Also, another EGF-like domain is located at the C-terminus. Expression of VWA2 is induced in stage II, III and IV colon cancers and colon adenomas and is considered a novel serum marker for the diagnosis of early-stage colon cancer.

VWA2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 177 amino acids (341-517 a.a) and having a molecular mass of 19.3kDa.
The VWA2 is expressed with an amino-terminal hexahistidine tag and purified by proprietary chromatographic techniques.
