• Background

  • Background

    Complement C3b is a central protein fragment generated from the cleavage of complement component C3, playing a crucial role in the activation of the complement system. C3b functions as an opsonin, tagging pathogens for phagocytosis, and participates in the formation of C5 convertase. It is essential in innate immunity, pathogen clearance, and modulation of adaptive immune responses, making it a valuable tool in immunology and infectious disease research.
