    Histamine Enzymatic Assay Kit for Seafood

    Order No.: ME70AER

    The Histamine Enzymatic Assay kit is a colorimetric enzymatic kit for the determination of histamine in seafood.

    【Summary】

    Histamine is a contaminant sometimes found in seafood when improperly handled. High levels of histamine in seafood can cause scombroid poisoning. Quality tuna has histamine levels below 50 ppm. The amount of histamine can be determined using ELISA or LC-MS. However these traditional methods require very expensive instrumentation and time consuming sample preparation procedures.

    The Histamine Enzymatic Assay Kit uses an enzymatic assay to detect histamine. The kit enables international and government regulatory agencies, food manufacturers and processors, as well as quality assurance organizations, to detect histamine in animal matrices in response to customer concerns about food safety.

    【Intended Use】

    The Histamine Enzymatic Assay kit is a colorimetric enzymatic kit for the determination of histamine in seafood.

    【Use Principles】

    The Histamine Enzymatic Assay Kit measures the chemical reduction of a dye molecule using a histamine-specific enzyme. The color change caused by reduction of the dye (measured by the absorbance at 450nm) is related to the amount of histamine present in the sample. The kit uses a brief Clearing Reagent treatment to eliminate interference of the enzymatic reaction.

    【Cross Reactivity】

    Histamine 100%
