The OSP ELISA kits listed below are analytical tools for measuring concentrations of OSP in various samples. OSP is an alternative name for the human CLDN11 gene, which encodes the protein, claudin 11. It has been mentioned that OSP plays a role in cell adhesion and spermatogenesis, among other functions. Structurally, the CLDN11 protein is described to be 207 amino acid residues in length and 22 kilodaltons in mass. It is localized to the cell membrane of the cell. Other names for this target antigen include HLD22 and OTM. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
