  • Product overview

    Abcam’s Complement C5a mouse ELISA Kit (ab193718) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of mouse Complement C5a in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for mouse Complement C5a coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures Complement C5a present in the samples. The wells are washed and biotinylated anti-mouse Complement C5a antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of Complement C5a bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Function

    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).
  • Involvement in disease

    Defects in C5 are the cause of complement component 5 deficiency (C5D) [MIM:609536]. A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis.
    Note=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).

Customer reviews and Q&As


For the ab193718 Mouse Complement C5a ELISA Kit, the antibodies used in the kit detect the C5a portion, but that doesn’t rule out the possibility of it also recognizing non-cleaved C5 since the region is included in the non-cleaved portion too. There could be some steric hindrance, but we have not determined that ourselves, and would need to be tested.
