Anti-VAKTI antibodies enable researchers to detect and measure the VAKTI antigen in biological samples. This target is a reported synonym of the SPINK5 gene, which encodes serine peptidase inhibitor Kazal type 5. This protein is known to function in cell differentiation and nervous system development, among other biological roles. The human version of VAKTI has a canonical amino acid length of 1064 residues and a protein mass of 120.7 kilodaltons, although 3 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in many tissues, such as the cervix and esophagus. Other names for this target antigen include LEKTI, LEKTI, and LETKI. Indicated applications for VAKTI antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunocytochemistry, and Immunohistochemistry.
