The Human Gastrin-Releasing Peptide (GRP) ELISA Kit is specifically designed for the accurate measurement of GRP levels in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, guaranteeing precise and consistent results, making it perfect for various research purposes.GRP is a vital neuropeptide that plays a key role in regulating various physiological processes, including gastrointestinal functions, neurotransmission, and immune responses.
Its dysregulation has been linked to several diseases, such as certain cancers and inflammatory disorders, making it a valuable biomarker in understanding these conditions and developing potential treatments.Overall, the Human GRP ELISA Kit provides researchers with a powerful tool to investigate the role of GRP in health and disease, ultimately advancing our understanding of these complex biological processes.

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.
