The Human Diamine Oxidase (DAO) ELISA Kit is specifically designed for the precise measurement of Diamine Oxidase levels in human serum, plasma, and cell culture supernatants. With its superior sensitivity and accuracy, this kit delivers consistent and dependable results, making it an excellent choice for various research applications.Diamine Oxidase is an important enzyme involved in the breakdown of histamine in the body, playing a critical role in regulating histamine levels and preventing histamine intolerance. Abnormal DAO levels have been associated with conditions such as food intolerance, allergy, and gastrointestinal disorders, making it a valuable biomarker for studying these conditions and developing potential treatment strategies.
With the Human DAO ELISA Kit, researchers can easily and effectively measure Diamine Oxidase levels, providing valuable insights into histamine metabolism and associated health conditions. Get your kit today and advance your research efforts in the field of histamine intolerance and related disorders.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
