These TLSP ELISA kits are immunodetection tools for measuring the levels of TLSP in biological samples. TLSP is an alias name of the human KLK11 gene, which encodes the protein, kallikrein related peptidase 11. Notably, TLSP is known to play a role in proteolysis, among other functions. The KLK11 protein is 282 amino acid residues in length and 31.1 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. Its subcellular localization is in the golgi and is secreted. In terms of tissue specificity, it is reported to be expressed in the brain, skin and prostate. This protein is known to be cleaved and glycosylated. Other names for this target antigen include PRSS20 and kallikrein-11.
