The Human Interleukin 28B (IL28B) ELISA Kit is a highly reliable tool for the accurate measurement of interleukin 28B levels in human samples such as serum, plasma, and cell culture supernatants. This kit boasts exceptional sensitivity and specificity, ensuring precise and reproducible results for a variety of research purposes.Interleukin 28B is a key cytokine involved in the immune response against viral infections, particularly hepatitis C virus.
Its levels are associated with treatment response and disease progression in hepatitis C patients, making it a valuable biomarker for understanding and managing this condition. Researchers can use this kit to study the role of interleukin 28B in viral infections and explore its potential as a therapeutic target.

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.
