PTPRS ELISA kits are immunoassay tools for the measurement of the protein protein tyrosine phosphatase receptor type S, which is encoded by the PTPRS gene in humans. Functionally, this protein is a reported cell surface receptor that binds to glycosaminoglycans, including chondroitin sulfate proteoglycans and heparan sulfate proteoglycan. The canonical protein structure is reported to have an amino acid length of 1948 residues, a mass of 217 kDa, and is a member of the Protein-tyrosine phosphatase protein family. It is known to be localized in the cell membrane and is notably expressed in peripheral blood plasmacytoid dendritic cells. As many as 7 protein isoforms have been reported. The protein has been noted to be post-translationally cleaved and glycosylated. Other alias names for this target include R-PTP-S, R-PTP-sigma, receptor-type tyrosine-protein phosphatase S, protein tyrosine phosphatase PTPsigma, receptor-type tyrosine-protein phosphatase sigma, and PTPSIGMA.
The detection range for different PTPRS ELISA kits can vary, with some assays measuring target concentrations as low as 0.156 ng/mL and as high as 50 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
