Anti-TSA2 antibodies are used in antigen-specific immunodetection in biological samples. The target TSA2 is a known alias name of the protein radial spoke head component 1, encoded by the RSPH1 gene in humans. This 309-amino acid residue protein is known to functions as part of axonemal radial spoke complexes that play an important part in the motility of sperm and cilia. It is localized to the cytoplasm of the cell. In terms of tissue expression, it is reported to be expressed in trachea, lungs, airway brushings, and testes. Indicated applications for TSA2 antibodies listed below include ELISA and Western Blot.
