The LETKI ELISA kits listed below are analytical tools for measuring concentrations of LETKI in various samples. LETKI is an alternative name for the human SPINK5 gene, which encodes the protein, serine peptidase inhibitor Kazal type 5. It has been mentioned that LETKI plays a role in cell differentiation and nervous system development, among other functions. Structurally, the SPINK5 protein is 1064 amino acid residues in length and 120.7 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be highly expressed in the thymus and stratum corneum. This protein is known to be cleaved. Other names for this target antigen include LEKTI and LEKTI. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
