Description: Recombinant Human CD55/DAF Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Asp35-Ser353) of human CD55/DAF (Accession #NP_000565.1) fused with a 6×His tag at the C-terminus.
Alternate Names: CD55, CR, CROM, DAF, TC, CROM, DAF, TC
SWISS: P08174
GeneID: 1604
Species: Human
Purity: ≥ 95 % as determined by SDS-PAGE.
Storage: Store at -20 ℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Background: This protein is a glycoprotein involved in the regulation of the complement cascade. Binding of the encoded protein to complement proteins accelerates their decay, thereby disrupting the cascade and preventing damage to host cells. Antigens present on this protein constitute the Cromer blood group system (CROM).
Bio-Activity: 1.Measured by its binding ability in a functional ELISA. Immobilized Human DAF/CD55 at 0.5 μg/mL (100 μL/well) can bind Human CD97 with a linear range of 0.3-23.8 ng/mL.|2.Measured by its binding ability in a functional ELISA. Immobilized APC anti-human CD55 Antibody at 1 μg/mL (25 μL/well) can bind Recombinant Human CD55 with a linear range of 0.5-3.2 ng/mL.
