Serotonin (5-hydroxytryptamine, 5-HT) plays unequivocally a most important role in the normal physiology amongst higher eukaryotes, as do most neurotransmitters. The physiological roles of serotonin and its receptors range from appetite, regulation of the circadian rhythm, sexual behavior, memory and nociception. Serotonin is also involved in migraine and some psychiatric diseases such as depression anxiety and aggression1. Serotonin and its receptors also have an influence on the cardiovascular, pulmonary, gastrointestinal (GI) and genitourinary systems2.
To date, some fifteen serotonin receptors have been cloned and grouped into seven families (5-HT1-5-HT7) based on their signaling mechanisms. The 5-HT1 receptor class comprises 5 different receptors with ranging homology. Apart from 5-HT3, all serotonin receptors belong to the G-protein coupled receptor superfamily and therefore span the membrane seven times3.
The 5-hydroxytryptamine receptor 1B (5-HT1B) is involved in several physiological behaviors and psychiatric diseases, including locomotor activity, drug abuse reinforcement, migraine, anxiety states and aggressive behaviors1.
Pharmacological studies suggest that 5-HT1B is expressed by both serotonergic and non-serotonergic neurons. In the nervous system, this receptor is located in the axon terminal of the plasma membrane of unmyelinated axons. It is predominantly localized on pre-synaptic membranes. Signal transduction studies of the receptor indicate that this receptor is coupled negatively to adenylyl cyclase as its activation induces a decrease in adenylyl cyclase activity1.
Anti-5HT1B Receptor (HTR1B) (extracellular) Antibody (#ASR-022) is a highly specific antibody directed against an epitope of the human 5-Hydroxytryptamine receptor 1B. The antibody can be used in western blot and immunohistochemistry applications. It has been designed to recognize 5HT1B receptor from human, rat, and mouse samples.
Anti-5HT1B Receptor (HTR1B) (extracellular)-ATTO Fluor-488 Antibody (#ASR-022-AG) is directly labeled with an ATTO-488 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-488 label is analogous to the well-known dye fluorescein isothiocyanate (FITC) and can be used with filters typically used to detect FITC. Anti-5HT1B Receptor (HTR1B) (extracellular)-ATTO Fluor-488 Antibody is specially suited to experiments requiring simultaneous labeling of different markers.
