This alpha 2 Macroglobulin antibody is un-conjugated
Application
Immunoelectrophoresis (IEP)
Specificity
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 been tested in double radial immunodiffusion against several ser of other species with the following results: bovine + dog ± cat + goat - monkey ++ rabbit + mouse - rat -
Characteristics
Precipitating polyclonal goat antiserum to human alpha-2 macroglobulin
Purification
Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies cross-reacting with other with other serum proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
Immunogen
Alpha-2 macroglobulin(clotting factor I) is the major protein in the alpha-2 region of human serum after separation by immunoelectrophoresis. The concentration in normal plasma is about 2.5 mg/ml. It is a large polymer and a strong antigen. It forms about one third in the total of the alpha-2 globulins. The protein is isolated by ammonium sulphate precipitation, ion exchange chromatography, gelfiltration and preparative starch block electrophoresis. In the purification the activation of kallikrein is avoided, since it forms an irreversible bond with alpha-2 macroglobulin, thus contaminating the final immunogen. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Application Notes
In precipitating techniques as immunoelectrophoresis and single or double radial immuno-diffusion (Mancini, Ouchterlony) to identify the presence of alpha-2 macroglobulin in human plasma or other body fluids or to determine its concentration. This antiserum is not intended for use in non-precipitating antibody binding or other highly sensitive assays, but this does exclude such use if proper controls are included.
Restrictions
For Research Use only
Format
Lyophilized
Concentration
Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal goat serum. Antibody titre: Precipitin titre 1:64 when tested against pooled normal human plasma in agar-block immunodiffusion titration. No foreign proteins ad
The reactivity of the antiserum is restricted to human alpha-2 macroglobulin. In immunoelectro-phoresis and radial immunodiffusion, using various antiserum concentrations against normal human plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified alpha-2 macroglobulin. No reaction is obtained with any other plasma protein components or serum
