The Chicken Interleukin-4 (IL4) ELISA Kit is specifically designed for the accurate measurement of interleukin-4 levels in chicken serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit provides reliable and reproducible results, making it ideal for a variety of research applications.Interleukin-4 is a key cytokine involved in modulating the immune response by promoting Th2 cell differentiation and antibody production.
It plays a crucial role in allergic responses, autoimmune diseases, and inflammatory conditions, making it a valuable biomarker for studying immune disorders and potential therapeutic interventions.Overall, the Chicken Interleukin-4 (IL4) ELISA Kit offers researchers a powerful tool for investigating the role of interleukin-4 in chicken immune function and disease pathogenesis.

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.
