Complement C4 anticorps (cleaved)

N° du produit ABIN457958

Détail du produit anti-Complement C4 anticorps

Antigène: Complement C4 (C4) (Complement 4 (C4))

Épitope: cleaved

Reactivité: Humain

Hôte: Chèvre

Clonalité: Polyclonal

Conjugué: Cet anticorp Complement C4 est non-conjugé

Application: Immunoelectrophoresis (IEP), Immunodiffusion (ID), Radial Immunodiffusion (RID)

Specificité: The antiserum does not cross react with any other component of human plasma. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins since they frequently share antigenic determinants. of this antiserum has not been tested in detail.

Attributs du produit: Precipitating polyclonal goat antiserum to the C4 component of human complement

Purification: Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies reacting with other plasma proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.

Immunogène: C4 and C2 represent substrates for activated C1. Both components are present in serum in an inert form. C4 is composed of 3 polypeptide chains of three different types, alpha, beta, gamma . One of the chains is cleaved by the action of activated C1, resulting in activation of C4 exposing an binding site for the next component in the sequence, C2. C4 has a molecular weight of 205.000 and is present in plasma in an average concentration of 600 µ g/ml. The activation of C4 yields two peptide fragments: C4a (MW 8,000) and C4b (MW 198,000). This process shows a considerable degree of similarity to the activation of the components C3 and C5. The C4 is isolated as a homogenous protein for use in antiserum production. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Isotype: IgG

Information d'application

Indications d'application: In precipitating techniques as immunoelectrophoresis and single or double radial immunodiffusion to identify the presence of C4 containing complexes in human plasma or other body fluids or to determine its concentration. The presence of non precipitating antibodies has not been assayed. This does not exclude the use of the antiserum in more sensitive non-precipitating antibody-binding techniques if proper controls are included.

Restrictions: For Research Use only

Sujet: The reactivity of the antiserum is restricted to C4. In immunoelectrophoresis and radial immunodif-fusion (Ouchterlony), using various antiserum concentrations against fresh normal human plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified C4 protein. Activated C4b may also react with the antiserum. No reaction is obtained with any other plasma protein component or serum
