Histamine H3 Receptor Activators

Santa Cruz Biotechnology now offers a broad range of Histamine H3 Receptor Activators. Histamine is an inflammatory mediator that is ubiquitously expressed and has a broad range of pharmacologic effects. The effects of histamine are mediated by a family of G protein-coupled receptors, the Histamine H1, H2, H3 and H4 Receptors. Histamine H3 Receptor Activators offered by Santa Cruz activate Histamine H3 Receptor and, in some cases, other inflammation and immune response related proteins.
