Pools of purified homogenous IgG2a and IgG2b isolated from rat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
Rat IgG2ab, subclass specific.
The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested. The reactivity of the antiserum is directed to the subclasses IgG2a and IgG2b. It does not react with other subclasses of IgG, IgG/Fab fragments, IgM and IgA or any non-Ig protein in rat serum, as tested by immunoelectrophoresis and double radial immunodiffusion. In immunocytochemical and immunohistochemical staining for the detection of IgG2 at the cellular and subcellular level of appropriately treated cell and tissue substrates. to demonstrate circulating IgG2 antibodies in serodiagnostic microbiology and autoimmune diseases. to identify a specific antigen using a reference antibody of rat origin known to be of the IgG2 isotype in the middle layer of the indirect test procedure. in non-isotopic assay methodology (e. g. ELISA) to measure IgG2 in rat serum or other body fluids. As a second step an avidin or streptavidin conjugate of the user's choice has to be used This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labeled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions for histochemical and cytochemical use are usually between 1:100 and 1:250. in ELISA and comparable non-precipitating antibody-binding assays between 1:2.000 and 1:10000 depending on the method used.
