Histamine (also referred to as beta-imidazolethylamine) is usually classified as an amine molecule because of its ammonia structure and it mainly stored in the form of granules within the tissues of mast cells. It can also be stored in blood cells which are called basophils that are found to be harbouring histamine-containing granules. Histamine is formed via the removal of a carboxyl group from the histidine molecule and it is found to be present in almost every tissue in the body.
At present there are four receptors that have been identified which are called H1, H2, H3 and H4. Histamine needs to bind to its receptors in order to carry out its specific function and these receptor can be found on the cell surface. It has been linked to number of different functions which include increasing permeability, helping with contraction of smooth muscles, stimulating gastric acid secretion within the stomach, lowering blood pressure and increasing the heart rate. Histamine activity can be inhibited by the use of anti-histamines, these are able to prevent histamines from binding to their receptors and this has be particularly useful in treating allergies and healing peptic ulcers.
This ELISA assay is based on a competitive procedure and during the sample preparation histamine is quantitatively acylated, this kit is designed so that it can be used with many different animal species and biological fluids.
Histamine ELISA kit is intended for measuring for in vitro quantitative levels of histamine (beta-imidazolethylamine) in EDTA-plasma and many other biological sample types. This assay has a minimum detection level of 0.2 ng/ml.
The minimum sensitivity limit of histamine (beta-imidazolethylamine) using this human histamine ELISA kit was approximately 0.2 ng/ml. The dynamic assay range for this kit is 0.5 – 50 ng/ml.
