Anti-WAS antibodies are used in the immunodetection of the protein WASP actin nucleation promoting factor. In humans, the canonical protein has a reported length of 502 amino acid residues and a mass of 52.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be highly expressed in the thymus. WAS is known to be involved with epidermis development. Post-translational modifications have been described, including phosphorylation. The WAS gene has been associated with the disease, Wiskott-Aldrich syndrome. Synonyms for this target antigen include SCNX, THC, THC1, WASP, WASPA, actin nucleation-promoting factor WAS, eczema-thrombocytopenia, and IMD2. WAS gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of WAS antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
