The General Glucocorticoid (GC) ELISA Kit is a reliable and accurate tool for measuring glucocorticoid levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is designed with high sensitivity and specificity to ensure precise and reproducible results for various research applications.Glucocorticoids are steroid hormones that play a crucial role in regulating metabolism, immune response, and stress levels in the body. Dysregulation of glucocorticoid levels has been linked to various health conditions such as inflammation, autoimmune disorders, and metabolic diseases.
Therefore, this ELISA kit is essential for researchers studying the role of glucocorticoids in these conditions and developing potential therapeutic interventions.Overall, the General Glucocorticoid (GC) ELISA Kit is a valuable tool for researchers looking to accurately measure glucocorticoid levels and better understand their role in health and disease.
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 condition. 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.
