Rat Interleukin 21 (IL-21) ELISA Kit

The Rat Interleukin-21 (IL21) ELISA Kit is a reliable and accurate tool designed for the detection of IL21 levels in rat serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring precise and reproducible results for various research applications.Interleukin-21 is a key cytokine involved in immune response regulation, particularly in the development and function of T cells and B cells.

It plays a critical role in inflammatory conditions, autoimmune diseases, and cancer, making it a valuable biomarker for studying these diseases and potential therapeutic targets.Overall, the Rat Interleukin-21 (IL21) ELISA Kit provides researchers with a reliable method to assess IL21 levels in rat samples, enabling a deeper understanding of the immune response and potential treatment strategies for various diseases.

Product Name:Rat Interleukin 21 (IL-21) ELISA Kit
Product Code:RTDL00556
Size:96 Assays
Target:IL21
Synonyms:Za11
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)83-10091
EDTA plasma (n=5)90-10396
Heparin plasma (n=5)90-9994
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.
