COMPLEMENT C9 FROM HUMAN SERUM FROZEN SOLUTION

Application

Complement C9 from human serum is an essential part of the terminal complement system. It has been a topic in cancer research, where extracellular phosphorylation by ecto-PK of K562 cells on serine residues may serve as a protective mechanism against complement in tumor cells. Additionally, it can be used as a biomarker (in fucosylated form) for squamous cell lung cancer, as patients tend to show elevated levels of C9 protein.

Biochem/physiol Actions

Complement component C9 is the final component of the membrane attack complex (MAC) responsible for cell lysis by complement. CD59 binds to both C8 and C9 and prevents assembly of an active MAC, protecting cells against lytic activity.

Quality

Functionally pure by a sensitive hemolytic assay using deficient sera.

Physical form

Supplied as a solution in phosphate buffered saline, pH 7.2.
