Rabbit IgG

Preparation Note

Prepared by the two-step glutaraldehyde method described by Avrameas, S., et al., Scand. J. Immunol., 8, Suppl. 7, 7 (1978).

Physical form

Lyophilized from 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 0.01% thimerosal.


Monoclonal Anti-Rabbit IgG (γ-chain specific)-Peroxidase antibody can be used in chemiluminescent western blot at 1:10,000 dilutions in human gastric and pancreatic carcinoma cell lines and immunohistochemistry (at 1:200 dilutions in formalin-fixed, paraffin-embedded sections).

The mouse monoclonal anti-Rabbit IgG (heavy chain-specific) peroxidase conjugated antibody can be used as a secondary antibody for western blot analysis of protein preps from E. coli cultures at a concentration of 1:10000 diluted in PBSt for 1 hour at room temperature.

General description

Rabbit IgGs are often used as primary antibodies in several immunological assays. Thus, polyclonal anti-rabbit IgGs are usually used as secondary antibodies in such applications. However, polyclonal antibodies to rabbit IgGs can also cross-react with IgGs from other species, especially with human IgGs, and thereby lead to a lack of specificity in test results. The use of monoclonal anti-rabbit IgG that is specific for only rabbit IgG improves the accuracy of immunological assays and thus, can be useful for various research applications.

The product recognizes an epitope located on the γ (heavy)-chain of rabbit IgG. In immunoblotting, the antibody recognizes both native and denatured forms of rabbit IgG. In ELISA, the antibody is specific for rabbit IgG, and shows no cross-reactivity with rabbit IgA and IgM or human IgG, IgA, and IgM. No cross reaction is observed with IgG from the following species: bovine, cat, chicken, dog, goat, guinea pig, horse, pig, rat, or sheep.
