These PTPsigma ELISA kits are immunodetection tools for measuring the levels of PTPsigma in biological samples. PTPsigma is an alias of the human PTPRS gene, which encodes the protein, protein tyrosine phosphatase receptor type S. Notably, PTPsigma is known to play a role in brain development, among other functions. The PTPRS protein is 1948 amino acid residues in length and 217 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is notably expressed in peripheral blood plasmacytoid dendritic cells. This protein is known to be cleaved and glycosylated.
