Product details
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Supportteam to know which antibody pair is suitable for this protein.

Function
Pore-forming component of the membrane attack complex (MAC), a multiprotein complex activated by the complement cascade, which inserts into a target cell membrane and forms a pore, leading to target cell membrane rupture and cell lysis (PubMed : 22832194, PubMed : 26841837, PubMed : 26841934, PubMed : 27052168, PubMed : 30552328, PubMed : 6177822, PubMed : 9212048, PubMed : 9634479). The MAC is initiated by proteolytic cleavage of C5 into complement C5b in response to the classical, alternative, lectin and GZMK complement pathways (PubMed : 39914456, PubMed : 39814882, PubMed : 9212048, PubMed : 9634479). The complement pathways consist in a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system (PubMed : 9212048, PubMed : 9634479). Constitutes the pore-forming subunit of the MAC complex : during MAC assembly, C9 associates with the C5b8 intermediate complex, and polymerizes to complete the pore (PubMed : 26841934, PubMed : 30111885, PubMed : 30552328, PubMed : 34752492, PubMed : 4055801, PubMed : 6177822).
Sequence similarities
Belongs to the complement C6/C7/C8/C9 family.
Post-translational modifications
Thrombin cleaves factor C9 to produce C9a and C9b.. Phosphorylation sites are present in the extracellular medium.. Initially, positions and connectivity of disulfide bonds were based on peptide sequencing done for the human protein (PubMed:8603752). The crystal structures for the human and mouse proteins corrected the positions and connectivities of the disulfide bonds (PubMed:30111885). The distance between Cys-57 and Cys-94 in the monomeric mouse protein precludes formation of a disulfide bond, contrary to what is seen in the structure of the human polymeric form of the protein (Probable).
