The Human Pepsinogen A (PGA) ELISA Kit is a highly reliable and accurate tool for the quantitative measurement of pepsinogen A levels in human samples including serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, ensuring precise and consistent results for various research applications.Pepsinogen A is an important enzyme that plays a critical role in the digestion process, specifically in the breakdown of proteins in the stomach. Abnormal levels of pepsinogen A have been associated with gastric diseases such as gastritis, peptic ulcers, and gastric cancer, making it a valuable biomarker for the diagnosis and monitoring of these conditions.
With its user-friendly protocol and high-quality components, the Human PGA ELISA Kit from Assay Genie is a valuable tool for researchers studying gastric diseases and seeking to understand the role of pepsinogen A in these conditions. Trust in this ELISA kit for accurate and reliable results in your research endeavors.

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 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.
