The General Cortisol Cor ELISA Kit from Assay Genie is a cutting-edge tool for measuring cortisol levels in a variety of biological samples. Whether analyzing serum, plasma, or cell culture supernatants, this kit provides researchers with precise and reliable results, thanks to its high sensitivity and specificity.Cortisol, often referred to as the "stress hormone," plays a crucial role in the body's response to stress and regulation of various physiological processes. Imbalances in cortisol levels have been associated with conditions such as anxiety, depression, and obesity, highlighting the importance of accurate measurement in research and clinical settings.
With the General Cortisol Cor ELISA Kit, scientists can gain valuable insights into the role of cortisol in health and disease, paving the way for innovative approaches to treatment and management of cortisol-related disorders. Trust Assay Genie for quality and performance in cortisol testing.

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.
