Anti-5-HT1B antibodies enable researchers to detect and measure the 5-HT1B antigen in biological samples. This target is a reported synonym of the HTR1B gene, which encodes 5-hydroxytryptamine receptor 1B. This protein is known to function in chemical synaptic transmission, among other biological roles. The human version of 5-HT1B has a canonical amino acid length of 390 residues and a protein mass of 43.6 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the cerebral cortex and colon. This target antigen may also be known as 5-HT-1D-beta. Western Blot is the most common application for the 5-HT1B antibodies listed below. ELISA and Immunofluorescence are also common applications.
