Antigen: mouse IP receptor N-terminal amino acids 3-16 conjugated to KLH . Host: rabbit . Cross Reactivity: (+) mouse and rat IP receptor; (-) human IP receptor . Application(s): WB . The IP receptor is a GPCR that mediates the action of PGI2. It participates in signal transduction of the pain response, cardioprotection, and inflammation. There is a significant amino-terminal truncation of the human IP receptor compared to the mouse receptor. This antibody is useful only for immunochemical analysis of mouse and rat samples.
