C3b is a vital component of the immune system, playing a crucial role in the complement pathway. It aids in opsonization, marking pathogens for destruction by phagocytes. Additionally, C3b contributes to the formation of the membrane attack complex, which can directly lyse target cells. Understanding C3b’s functions is essential for advancing immunological research and therapies. https://www.creative-biolabs.com/complement-therapeutics/target-c3b-2022.htm
