Histamine food ELISA kit is intended for detecting quantitative amounts of histamine derivatives present in food extracts. This assay has a minimum analytical sensitivity limit of 0.15 ng/ml.
Histamine is a chemical that is present in all cells of the human body and is also a natural component of many different foods. It is a compound that is involved in a number of processes such as the immune system, central nervous system and proper digestion. Due to the fact that it is able to travel through the bloodstream, histamine is able to affect the brain, gut, lungs, cardiovascular system and skin, this makes it very difficult to pinpoint and diagnose since it is able to contribute to a host of different problems.
The following histamine food ELISA kit is designed for measuring quantitative concentrations of histamine derivatives found in food extracts. The procedure uses acylation reagent where histamine has been quantitatively derivatized into N-acylhistamine. Histamine is essentially a product of decomposition of histidine that is the result of growth of certain bacteria that are present in seafood. Fish that contain high levels of histamine are found to be linked to a number of examples of poisoning (also referred to as scombroid poisoning).
