  • 产品描述：

    Among the classical, alternative, and lectin pathways for complement activation, C3 is central to the function of all three pathways and C3 convertase-induced production of cleavage products mediates numerous biological activities and then acts on the C5 convertase. C3a and C3b binding to complement receptors C3aR and CD36, respectively, play a key role in the regulation of human T cell responses via intracellular C3 activation mediated by cathepsin L (CTSL). When C3 is split into C3b, an internal thioester link is exposed, allowing C3b to connect to hydroxyl groups on nearby carbohydrates and proteins in a stable covalent manner.

    The recombinant C3 antibody was generated in vitro through inserting cloned C3 genes into expression vectors. The expression vector was then inserted into a mammalian cell to express this C3 antibody. It has been validated in ELISA, WB, IHC, FC. Every step in the production was controlled strictly.  You have no worries about the quality.

  • 功能：
    C3 plays a central role in the activation of the complement system. Its processing by C3 convertase is the central reaction in both classical and alternative complement pathways. After activation C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates.; Derived from proteolytic degradation of complement C3, C3a anaphylatoxin is a mediator of local inflammatory process. In chronic inflammation, acts as a chemoattractant for neutrophils. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes.; Acts as a chemoattractant for neutrophils in chronic inflammation.; adipogenic hormone that stimulates triglyceride (TG) synthesis and glucose transport in adipocytes, regulating fat storage and playing a role in postprandial TG clearance. Appears to stimulate TG synthesis via activation of the PLC, MAPK and AKT signaling pathways. Ligand for C5AR2. Promotes the phosphorylation, ARRB2-mediated internalization and recycling of C5AR2.
