A Rat Monoclonal Antibody Against the Chromatin Remodeling Factor CHD5

CHD5 (chromodomain/helicase/DNA-binding protein 5) is a member of the CHD subfamily of chromatin remodeling Swi/Snf proteins, and has been recently identified as a tumor suppressor in a diverse range of human cancers. We report here on the establishment of a hybridoma cell line for producing a monoclonal antibody against CHD5 by the rat medial iliac lymph node method. Immunoblotting analyses indicated that this antibody, MAb 5A10, specifically recognizes endogenous CHD5. In immunostaining using the antibody, a nuclear staining pattern was observed. The monoclonal antibody will be useful in immunoblotting and immunolocalization experiments in a variety of cells and tissues, as well as in further studies of the biological function and cellular dynamics of this protein.
