Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. of this antiserum has not been tested in detail.
Attributs du produit
Precipitating polyclonal rabbit antiserum to human complement
Purification
Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies reacting with other human serum proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
Immunogène
The complement complex of C3c, C3d and C4 is isolated and purified from pooled normal human plasma. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Isotype
IgG
Indications d'application
In precipitating techniques as immunoelectrophoresis and single and double radial immuno-diffusion (Mancini, Ouchterlony) to identify the presence of complement 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 non-precipitating antibody-binding techniques if proper controls are included. Determinations of individual complement components can be very useful in defining the exact location of a defect.
Restrictions
For Research Use only
Format
Lyophilized
Concentration
Total protein and IgG concentrations in the antiserum are comparable to those of normal pooled rabbit serum. No foreign proteins added. Antibody titre: Precipitin titre not less than 1:32 when tested against normal human plasma in agar-block immunodiffusi
The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C, prolonged storage at or below -20°C. Reconstitute the lyophilized antiserum by add ing 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C, not ref rozen, and preferably used the same day.
Antigène
Complement Complex C3c, C3d, C4
Sujet
Tested in immunoelectrophoresis and radial immunodiffusion, using various antiserum concen-trations against human plasma a single precipitin line is obtained in the beta-1 region and shows a reaction of full identity with the purified immunogen. The antiserum does not react with any other protein component of human serum or plasma
