Anti-5HT3B Receptor (HTR3B) (extracellular) Antibody (#ASR-032) is a highly specific antibody directed against an epitope of rat Serotonin receptor 3B. The antibody can be used in western blot  and immunohistochemistry applications. It recognizes an extracellular epitope and can potentially detect 5-HT3B in living cells. It has been designed to recognize 5-HT3B from rat and mouse samples. The antibody is unlikely to recognize the receptor from human samples.
