Anti-PSPase antibodies enable researchers to detect and measure the PSPase antigen in biological samples. This target is a reported synonym of the PSPH gene, which encodes phosphoserine phosphatase. This protein is known to function in in utero embryonic development, among other biological roles. The human version of PSPase has a canonical amino acid length of 225 residues and a protein mass of 25 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include PSP, PSPHD, and L-3-phosphoserine phosphatase. Some PSPase antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
