Anti-PPAP2B antibodies enable researchers to detect and measure the PPAP2B antigen in biological samples. This target is a reported synonym of the PLPP3 gene, which encodes phospholipid phosphatase 3. This protein is known to function in Bergmann glial cell differentiation and blood vessel development, among other biological roles. The human version of PPAP2B has a canonical amino acid length of 311 residues and a protein mass of 35.1 kilodaltons. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Other names for this target antigen include Dri42, LPP3, and PAP2B.
