Anti-TATI antibodies enable researchers to detect and measure the TATI antigen in biological samples. This target is a reported synonym of the SPINK1 gene, which encodes serine peptidase inhibitor Kazal type 1. This protein is known to function in the regulation of intracellular calcium, among other biological roles. The human version of TATI has a canonical amino acid length of 79 residues and a protein mass of 8.5 kilodaltons. It is reported to be a secreted protein that is notably expressed in many tissues, such as the appendix and colon. Other names for this target antigen include PCTT, PSTI, and Spink3. Indicated applications for TATI antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
