Summary	Histamine (2-[4-imidazole]ethylamine) is a low-molecular-weight amine synthesized from L-histidine. It is produced by various cells throughout the body, including central nervous system neurons, gastric mucosa parietal cells, mast cells, basophils and lymphocytes. Histamine is a major biological mediator whose functions include, among many others, regulation of vascular smooth muscle, immune regulation, regulation of sleep-wake cycles and regulation of gastric acid secretion.1 The biological effects of histamine are mediated through four receptors (H1- H4 Histamine receptors) all of which belong to the 7-transmembrane domain, G protein-coupled receptor (GPCR) superfamily.H4 Histamine Receptor couples to Gi/G0 proteins and receptor activation leads to inhibition of adenylate cyclase, mobilisation of calcium from intracellular stores and activation of the mitogen-activated protein kinase (MAPK) cascade. 1, 2 H4 Histamine Receptor is largely expressed in haemopoietic cells including mast cells, eosinophils, dendritic cells and T lymphocytes. H4 Histamine Receptors modulate eosinophil migration and the selective recruitment of mast cells leading to amplification of histamine-mediated immune responses. In addition, H4 Histamine Receptors are involved in dendritic cell activation and the regulation of T lymphocyte cytokine production.2, 3These studies indicate that H4 Histamine Receptor is an attractive therapeutic target for the treatment of inflammatory disorders, such as allergy, asthma, chronic pruritus and autoimmune diseases.2, 3 Abgent is pleased to offer a highly specific antibody directed against an epitope located at the extracellular 1st loop of the human H4 Histamine receptor. Anti-Human H4 Histamine Receptor (extracellular) antibody (#AG1224) can be used in western blot and indirect flow cytometry applications, and recognizes H4 Histamine receptor from human samples.

Images	Flow cytometric analysis of Jurkat cells using Park7 (DJ-1) Antibody(green, APR12422G) compared to an isotype control of rabbit IgG(blue). APR12422G was diluted at 1:35 dilution. An Alexa Fluor? 488 goat anti-rabbit lgG at 1:400 dilution was used as the secondary antibody.   Western blot analysis of lysates from HL-60, A431, U-937 cell line (from left to right), using HRH4 Antibody( APR12422G). APR12422G was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysates at 35ug per lane.   Western blot analysis of human chronic myelogenous leukemia (K562) (lanes 1 and 3) and human promyelocytic leukemia (HL-60) (lanes 2 and 4) cell lysates: 1, 2.
