Displaying 4 results of Histamine Stable Isotopes Histamine stable isotopes refer to isotopically labeled forms of histamine, a biogenic amine involved in various physiological processes such as neurotransmission, immune response, and gastric acid secretion. These labeled isotopes are used in various research applications, including metabolic studies, pharmacological investigations, and diagnostic assays. By incorporating stable isotopes into histamine molecules, researchers can track the fate of the molecule in vivo and gain insights into its biological functions and mechanisms of action.
