Anti-CRTH2/GPR44 (extracellular) Antibody (#APR-062) is a highly selective antibody directed against an epitope of the rat Prostanoid DP2 receptor. The antibody can be used in western blot, immunohistochemistry and live cell flow cytometry applications. The antibody recognizes an extracellular epitope and can potentially be used for detecting the protein in living cells. It has been designed to recognize DP2 receptor from mouse and rat samples. It is unlikely to recognize the receptor from human samples.
