Anti-HPTPeta antibodies enable researchers to detect and measure the HPTPeta antigen in biological samples. This target is a reported synonym of the PTPRJ gene, which encodes protein tyrosine phosphatase receptor type J. This protein is known to function in B cell differentiation and cytokine-mediated signaling pathways, among other biological roles. The human version of HPTPeta has a canonical amino acid length of 1337 residues and a protein mass of 145.9 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the bone marrow, tonsil, and appendix. Other names for this target antigen include CD148, CD148, and DEP1. Indicated applications for HPTPeta antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
