  ANTIBODIES  

(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Background: Serotonin (5-hydroxytryptamine, 5-HT), originally discovered as a serum factor, plays an important role in regulating diverse biological processes in the central and peripheral nervous systems, the cardiovascular system and the fastrointestinal systems. The different functions of serotonin are thought to be mediated through specific receptors. Physiological, biochemical,and pharmacological studies have defined at least thirteen serotonin receptors. The thirteen receptors are grouped in seven subtypes according to operational, structural, and transductional properties. The 5-HT2 receptors (5-HT2AR, 5-HT2BR,and 5-HT2CR) may be considered as prototypes for the study of serotonin receptors. Their functions are mediated by the second messenger inositol polyphosphate in a G- protein coupled pathway. They are expressed in diverse tissues including brain, vascular smooth muscles, and platelets (reviewed in 3). However, the exact localization of 5-HT2 receptors in the CNS remains to be elucidated. The 5-HT2AR mRNAs have been found in only a few areas of the brain, including the frontal cortex, piriform cortex, ventro-caudal part of CA3, motor cranial nerve nuclei in the brainstem, and the ventral horn of the spinal cord. The 5-HT2CR mRNA has been found at high levels in many parts of the brain including retrosplenial piriform, and entorhinal cortex, anterior olfactory nucleus, substantia nigra pars compacta, several brainstem nuclei and the whole grey matter of the spinal cord. The 5-HT2BR is almost absent in the brain, but is abundantly expressed in stomach fundus. Monoclonal antibodies reacting specifically to 5-HT2AR, 5-HT2BR, and 5- HT2CR will be useful tools in determining the precise anatomical distribution of 5-HR2 receptors.
