Dieser Cortisol Binding Globulin Antikörper ist unkonjugiert
Applikation
Western Blotting (WB), ELISA, Immunoelectrophoresis (IEP)
Spezifität
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.
Produktmerkmale
Precipitating polyclonal rabbit antiserum to human cortisol binding globulin (transcortin)
Aufreinigung
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.
Immunogen
Cortisol binding globulin is an alpha-1 glycoprotein with a molecular weight of 55,700. It is bonding and transporting cortisol in plasma. The mean concentration in adult serum is about 50 µ g/ml. Elevated levels are observed in pregnancy. 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) to identify the presence of cortisol binding globulin 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 as ELISA and Western blotting if proper controls are included.

Format
Lyophilized
Rekonstitution
Reconstitute with 1 mL distilled water
Konzentration
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 1:16 when tested against normal human serum in agar-block immunodiffusio
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.
Tested in immunoelectrophoresis and radial immunodiffusion, using various antiserum concen-trations against human plasma 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
