Anti-BAF250B antibodies enable researchers to detect and measure the BAF250B antigen in biological samples. This target is a reported synonym of the ARID1B gene, which encodes AT-rich interaction domain 1B. This protein is known to function in chromatin remodeling and nervous system development, among other biological roles. The human version of BAF250B has a canonical amino acid length of 2319 residues and a protein mass of 243.9 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
