The 5-HT4R ELISA kits listed below utilize specific antibodies for the plate-based assay of 5-HT4R in various samples. 5-HT4R is another term for the HTR4 gene, which encodes the protein, 5-hydroxytryptamine receptor 4 in humans. It has been reported that 5-HT4R plays a role in chemical synaptic transmission and GPCR signaling pathways, among other functions. Structurally, the HTR4 protein is 388 amino acid residues in length and 43.8 kilodaltons in mass. However, as many as 9 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include 5-HT4 and 5-hydroxytryptamine (serotonin) receptor 4, G protein-coupled.
