Complement decay-accelerating factor, GPI-anchored,
DAF-GPI, CD_antigen: CD55.
CD55
belongs to the RCA (regulators of complement activation) family characterized
by 4-30 SCRs (short consensus repeats) in their plasma-exposed regions. CD55 is
widely expressed in malignant tumors and nevertheless functions as an inhibitor
of the complement system.
CD55 produced in Sf9 Baculovirus cells is a single,
glycosylated polypeptide chain containing 336 amino acids (35-362 a.a.) and
having a molecular mass of 36.8kDa (Migrates at 40-57kDa on SDS-PAGE under
reducing conditions).
CD55 is expressed with an 8 amino acid His tag at
C-Terminus and purified by proprietary chromatographic techniques.
