General 5-Hydroxyindoleacetic Acid (5-HIAA) ELISA Kit
The General 5-Hydroxyindoleacetic Acid (5-HIAA) ELISA Kit is a reliable and accurate tool for detecting levels of 5-HIAA in various biological samples, including serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit ensures precise and reproducible results, making it suitable for a wide range of research applications.5-HIAA is a metabolite of serotonin and is often used as a biomarker for serotonin production and turnover. It plays a crucial role in various physiological processes, including mood regulation, gastrointestinal function, and cardiovascular health.
Abnormal levels of 5-HIAA have been associated with conditions such as carcinoid tumors, depression, and irritable bowel syndrome, making it a valuable target for research and diagnostic purposes.Whether studying neurochemistry, gastrointestinal disorders, or oncology, the General 5-Hydroxyindoleacetic Acid (5-HIAA) ELISA Kit provides a reliable and accurate means of quantifying 5-HIAA levels in biological samples, offering valuable insights into the underlying mechanisms of various diseases and potential therapeutic interventions.

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 condition. 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.
