Generation of a monoclonal antibody for INI1/hSNF5/BAF47.

INI1/hSNF5/BAF47, which has an SNF5 domain, belongs to the SWI/SNF family. This family is known as ATP-dependent regulators of gene expression by remodeling chromatin structure during cell differentiation. However, the detailed function of INI1/hSNF5/BAF47 is unclear. Here we report the generation of a specific monoclonal antibody for INI1/hSNF5/BAF47 by the mouse iliac lymph node method. The obtained antibody recognized two isoforms of INI1/hSNF5/BAF47 in immunoblotting and precisely recognized the nuclear localization of INI1/hSNF5/BAF47 in immunostaining. This antibody can contribute to further elucidation of the mechanisms of gene expression regulation by INI1/hSNF5/BAF47 during cell differentiation.
