Description
Histamine is located in mast cells, endocrine cells of the gut, blood cells and in some cells of the peripheral and central nervous system. Histamine is a potent vasodilator when secreted by mast cells found in various tissues as a result of allergic hypersensitivity or inflammation. In the central nervous system, Histamine is putative neurotransmitter. In the brain, its highest content has been found in the hypothalamus and in certain areas of the mesencephalon. The Histamine antiserum has a sensitivity level capable of detecting the low level Histamine contents of the brain. The Histamine antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat hypothalamus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are 1/500 - 1/1000 in PBS/0.3% Triton X-100 Cy3 Technique and 1/4000-1/6000 in PBS/0.3% Triton X-100 biotin/avidin-HRP Technique . All staining is blocked by preabsorption of the antiserum with Histamine conjugate. Cross reactivity experiments indicate no cross reactivity with L-histidine or L-histidine containing peptides such as LH-RH.
