Anti-ACTRIB antibodies enable researchers to detect and measure the ACTRIB antigen in biological samples. This target is a reported synonym of the ACVR1B gene, which encodes activin A receptor type 1B. This protein is known to function in the apoptotic pathway and hair follicle development, among other biological roles. The human version of ACTRIB has a canonical amino acid length of 505 residues and a protein mass of 56.8 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the breast, urinary bladder, and appendix. This target antigen may also be known as ACVRLK4. Western Blot is the most common application for the ACTRIB antibodies listed below. ELISA and Immunohistochemistry are also common applications.
