The Human Pancreatic Polypeptide (PP) ELISA Kit is specifically designed for the precise measurement of pancreatic polypeptide levels in human serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, ensuring consistent and accurate results for various research applications. Pancreatic polypeptide is a critical hormone produced by the pancreas, playing a key role in regulating food intake and energy balance. Abnormal levels of pancreatic polypeptide have been linked to conditions such as diabetes, obesity, and gastrointestinal disorders, making it a valuable biomarker for studying these diseases and exploring potential therapeutic interventions.
With its user-friendly design and reliable performance, the Human Pancreatic Polypeptide (PP) ELISA Kit is an essential tool for researchers investigating the roles of pancreatic polypeptide in health and disease. Experience precise and dependable results with this advanced kit from Assay Genie.

Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

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.
