Complement & Innate Immunity

About Complement & Innate Immunity

Antibodies, ELISA kits, and proteins for studying the complement cascade and the innate immune sensors that provide the first line of host defense. The category spans the three complement activation pathways (classical, lectin, and alternative) and their components — C1q, C3, C4, C5, factors B and D, and the C5b-9 membrane attack complex — together with regulators (factor H, CD55, CD59), anaphylatoxin receptors (C3aR, C5aR1), and pattern-recognition sensors such as Toll-like and NOD-like receptors. Use it to source validated tools for complement activation, innate immune signaling, and complement-mediated disease across human and preclinical species.
