These 5HT3 ELISA kits are immunodetection tools for measuring the levels of 5HT3 in biological samples. 5HT3 is an alias of the human HTR3A gene, which encodes the protein, 5-hydroxytryptamine receptor 3A. Notably, 5HT3 is known to play a role in chemical synaptic transmission and signal transduction pathways, among other functions. The HTR3A protein is 478 amino acid residues in length and 55.3 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is reported to be expressed in cerebral cortex, amygdala, hippocampus, and testis. This protein is known to be glycosylated. Other names for this target antigen include 5-HT3A. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
