Anti-phosphodiesterase 1B antibodies are used for the immunodetection of the protein encoded by the PDE1B gene. In humans, the canonical protein has a reported length of 536 amino acid residues and a mass of 61.4 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Cyclic nucleotide phosphodiesterase protein family, it is known to be involved with monocyte differentiation and signal transduction pathways. Other names for this target antigen include PDE1B1, PDES1B, dual specificity calcium/calmodulin-dependent 3',5'-cyclic nucleotide phosphodiesterase 1B, and HEL-S-79p. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some phosphodiesterase 1B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
