Anti-B-ALPHA-1 antibodies enable researchers to detect and measure the B-ALPHA-1 antigen in biological samples. This target is a reported synonym of the TUBA1A gene, which encodes tubulin alpha 1a. This protein is known to function in cell division and nervous system development, among other biological roles. The human version of B-ALPHA-1 has a canonical amino acid length of 451 residues and a protein mass of 50.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. This target antigen may also be known as LIS3.
