The Human Nucleophosmin (NPM) ELISA Kit is specifically designed for the precise measurement of nucleophosmin levels in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is known for its excellent sensitivity and specificity, ensuring accurate and consistent results that are perfect for a variety of research purposes.Nucleophosmin, also known as NPM1, is a multifunctional protein involved in various cellular processes such as ribosome biogenesis, DNA repair, and regulation of cell proliferation.
Dysregulation of Nucleophosmin has been linked to several diseases including acute myeloid leukemia, making it a valuable biomarker for disease detection and monitoring.With the Human Nucleophosmin (NPM) ELISA Kit, researchers can easily quantify Nucleophosmin levels in human samples, advancing their understanding of its role in disease development and progression. This kit provides a reliable and efficient method for studying Nucleophosmin and its implications in various pathological conditions.
Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.

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.
