Anti-Histamine H2 Receptor antibodies enable researchers to detect and measure the Histamine H2 Receptor antigen in biological samples. This target is a reported synonym of the HRH2 gene, which encodes histamine receptor H2. This protein is known to function in chemical synaptic transmission and immune response pathways, among other biological roles. The human version of Histamine H2 Receptor has a canonical amino acid length of 359 residues and a protein mass of 40.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the duodenum and small intestine. Other names for this target antigen include H2R, H2R, and HH2R. Western Blot is a widely used application for the Histamine H2 Receptor antibodies listed below. In addition, ELISA is also a common application.
