Complement component 1q (C1q) is a crucial protein complex involved in the innate immune system’s complement pathway. C1q, together with C1r and C1s, comprises the C1 complex, which becomes active upon binding to antigen-antibody complexes. This activation triggers the classical complement pathway, a part of the immune system’s defense mechanism. Learn more, https://www.creative-biolabs.com/complement-therapeutics/target-c1q-474.htm.
