Anti-TMSB4X antibodies are used in the immunodetection of the protein thymosin beta 4 X-linked. In humans, the canonical protein has a reported length of 44 amino acid residues and a mass of 5.1 kDa. Its subcellular localization is in the cytoplasm. It is reported to be expressed in several hemopoietic cell lines and lymphoid malignant cells. A member of the Thymosin beta protein family, TMSB4X is known to play an important role in the organization of the cytoskeleton. Synonyms for this target antigen include PTMB4, TB4X, TMSB4, thymosin beta-4, prothymosin beta-4, t beta-4, thymosin, beta 4, X chromosome, and FX. TMSB4X gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 60 citations in the literature describe the use of TMSB4X antibodies in research. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
