Human Leucyl/Cystinyl Aminopeptidase (LNPEP) ELISA Kit
The Human Leucyl-Cystinyl Aminopeptidase (LNPEP) ELISA Kit is a powerful tool for the precise measurement of LNPEP levels in human samples such as serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, ensuring accurate and reproducible results for a variety of research purposes.LNPEP, also known as angiotensin IV receptor, is a key enzyme involved in the metabolism of peptides and plays a vital role in regulating blood pressure, kidney function, and other physiological processes.
Dysregulation of LNPEP has been implicated in various diseases including hypertension, kidney disorders, and metabolic syndromes, highlighting its importance as a potential therapeutic target and biomarker for disease progression.With its reliable performance and versatility, the Human LNPEP ELISA Kit is an essential tool for researchers studying the role of LNPEP in health and disease, offering valuable insights for the development of novel treatment strategies.

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.
