Human Interleukin 4 (IL-4) ELISA Kit

The Human Interleukin-4 (IL-4) ELISA Kit is specially designed to accurately measure interleukin-4 levels in human serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, ensuring precise and consistent results perfect for various research applications.Interleukin-4 is a key cytokine involved in regulating immune responses and inflammatory processes. It plays a crucial role in conditions such as allergies, asthma, and autoimmune diseases, making it a valuable biomarker for studying these diseases and potential treatment strategies.

With its high-quality components and easy-to-follow instructions, the Human Interleukin-4 (IL-4) ELISA Kit is an invaluable tool for researchers looking to delve deeper into the role of interleukin-4 in health and disease.

Product Name:Human Interleukin 4 (IL-4) ELISA Kit
Product Code:HUDL01517
Size:96 Assays
Target:IL4
Synonyms:BSF1, BCGF1 , B Cell Stimulatory Factor 1, Lymphocyte stimulatory factor 1, B Cell Growth Factor, Binetrakin, Pitrakinra
Detection Method:Sandwich
Range:15.625-1000pg/mL
Shelf Life:12 months
Note:For research use only
Recovery: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.
MatrixRecovery range (%)Average(%)
Serum (n=5)80-10291
EDTA plasma (n=5)81-9990
Heparin plasma (n=5)80-8984
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.
Sample 1:2 1:4 1:8 1:16
Serum (n=5) 82-96% 83-98% 81-99% 93-101%
EDTA plasma (n=5) 88-101% 86-95% 90-102% 80-93%
Heparin plasma (n=5) 80-91% 82-90% 95-104% 79-95%
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.
