Anti-STEP antibodies enable researchers to detect and measure the STEP antigen in biological samples. This target is a reported synonym of the PTPN5 gene, which encodes protein tyrosine phosphatase non-receptor type 5. This protein is known to function in protein dephosphorylation and signal transduction pathways, among other biological roles. The human version of STEP has a canonical amino acid length of 565 residues and a protein mass of 63.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the ER of cells and notably expressed in the kidney, duodenum, cerebral cortex, caudate, and appendix. STEP is a member of the Protein-tyrosine phosphatase protein family. Indicated applications for STEP antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
