The Bovine Visfatin (VF) ELISA Kit offered by Assay Genie is a powerful tool for detecting visfatin levels in bovine serum, plasma, and cell culture supernatants. With exceptional sensitivity and specificity, this kit delivers reliable and consistent results, making it a valuable asset for various research applications.Visfatin, also known as nicotinamide phosphoribosyltransferase (NAMPT), is a key protein involved in metabolic regulation, inflammation, and cell survival. Dysregulation of visfatin has been implicated in various metabolic disorders, including obesity, diabetes, and cardiovascular diseases.
Therefore, monitoring visfatin levels can provide valuable insights into these conditions and potentially aid in the development of therapeutic interventions.By utilizing the Bovine Visfatin ELISA Kit from Assay Genie, researchers can accurately quantify visfatin levels in bovine samples, allowing for a deeper understanding of its role in physiology and disease. Don't miss out on this cutting-edge research tool for your laboratory needs.
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.
