The Human Visceral Adipose Tissue-Derived Serine Protease Inhibitor (Vaspin) ELISA Kit is specially designed for the precise measurement of Vaspin levels in human samples such as serum, plasma, and cell culture supernatants. With its exceptional sensitivity and specificity, this kit delivers reliable and consistent results, making it a valuable tool for various research applications.Vaspin, also known as visceral adipose tissue-derived serine protease inhibitor, plays a key role in regulating insulin sensitivity and adipose tissue metabolism.
Dysregulation of Vaspin has been linked to obesity, type 2 diabetes, and metabolic disorders, highlighting its significance as a potential biomarker in these conditions.Researchers can rely on the Human Visceral Adipose Tissue-Derived Serine Protease Inhibitor (Vaspin) ELISA Kit to accurately quantify Vaspin levels, providing valuable insights into the mechanisms underlying metabolic diseases and paving the way for the development of targeted therapies.

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.
