A monoclonal antibody that specifically recognizes phosphatidylinositol-3,4,5-triphosphate (PIP3) but does not cross-react with structurally similar phospholipid antigens is advantageous for PIP3-specific immunoassay. The gene in the variable regions of the monoclonal antibody has been identified, which enables producing recombinant antibodies.

Un anticuerpo monoclonal que reconoce específicamente phosphatidylinositol-3,4,5-triphosphate (PIP3) pero cruz-no reacciona con los antígenos estructural similares del phospholipid es ventajoso para PIP3-specific immunoassay. El gene en las regiones variables del anticuerpo monoclonal se ha identificado, que permite producir los anticuerpos recombinant.
