Anti-LEKTI2 antibodies enable researchers to detect and measure the LEKTI2 antigen in biological samples. This target is a reported synonym of the SPINK9 gene, which encodes serine peptidase inhibitor Kazal type 9. This protein is a type of serine protease inhibitor which specifically inhibits KLK5. The human version of LEKTI2 has a canonical amino acid length of 86 residues and a protein mass of 9.8 kilodaltons. It is reported to be a secreted protein.
