Western Blotting (WB), ELISA, Immunodiffusion (ID), Immunoelectrophoresis (IEP)
特异性
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.
产品特性
Precipitating polyclonal rabbit antiserum to human beta-2 glycoprotein 1 (apolipoprotein H)
纯化方法
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.
免疫原
Beta-2 glycoprotein 1 has a molecular weight of 40,000. The mean concentration in adult serum is about 200 µ g/ml. Freund’s complete adjuvant is used in the first step of the immunization procedure.
In precipitating techniques as immunoelectrophoresis and single and double radial immuno-diffusion (Mancini, Ouchterlony) and electroimmunodiffusion (Laurell) to identify the presence of beta-2 glycoprotein 1 or to determine its concentration. The presence of non-precipitating anti-bodies has not been assayed. This does not exclude the use of the antiserum in non-precipitating antibody-binding techniques as ELISA and Western blotting if proper controls are included.

Lyophilized
浓度
Total protein and IgG concentrations in the antiserum are comparable to those of normal pooled rabbit serum. No foreign proteins added. Antibody titre: Measured by quantitative precipitin analysis. The amount of beta2 glycoprotein 1 precipitated by 1 ml a
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.

(Apolipoprotein H (Beta-2-Glycoprotein I) (APOH))
In bidimensional immunoelectrophoresis a single precipitin line is obtained 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
