  • 产品名称Anti-C5 / C5a抗体[557]
    参阅全部 C5 / C5a 一抗
  • 描述
    小鼠单克隆抗体[557] to C5 / C5a
  • 特异性This antibody reacts with an epitope on C5 and C5a. The antibody 557 is capable to inhibit the binding of C5a to the C5a receptor through a competitive mechanism, it does not block the cleavage of C5 into C5a and C5b.

Inhibition Assay Use at an assay dependent dilution.
Functional Studies Use at an assay dependent dilution.


  • 功能Activation of C5 by a C5 convertase initiates the spontaneous assembly of the late complement components, C5-C9, into the membrane attack complex. C5b has a transient binding site for C6. The C5b-C6 complex is the foundation upon which the lytic complex is assembled.
    Derived from proteolytic degradation of complement C5, C5 anaphylatoxin is a mediator of local inflammatory process. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes. C5a also stimulates the locomotion of polymorphonuclear leukocytes (chemokinesis) and direct their migration toward sites of inflammation (chemotaxis).
  • 疾病相关Complement component 5 deficiency
    An association study of C5 haplotypes and genotypes in individuals with chronic hepatitis C virus infection shows that individuals homozygous for the C5_1 haplotype have a significantly higher stage of liver fibrosis than individuals carrying at least 1 other allele (PubMed:15995705).

Thank you very much for your patience.

I have been checking with my lab colleagues the percentage of homology of the epitopes recognised by our anti C5 antibodies and the correspondent protein in bovine species. Unfortunately, I am afraid non...

Thank you for your enquiry. Ab11876 recognizes an epitope located within the alpha-chain of C5 that corresponds to C5a. Thus it recognizes both C5 and C5a. The antibody inhibits binding of C5a to the C5a receptor through a competitive mechanism. It...
