DCN produced in Sf9 Baculovirus cells is a single,glycosylated polypeptide chain containing 335 amino acids (31-359a.a.) andhaving a molecular mass of 37.1kDa. (Molecular size on SDS-PAGE will appear atapproximately 40-57kDa).DCN is expressed with a 6 amino acid His tag atC-Terminus and purified by proprietary chromatographic techniques. Purity >95% as determined by SDS-PAGE.
