Cayman’s Cortisol Express ELISA is a competitive assay that permits the rapid measurement of cortisol from biological samples, requiring only a two hour incubation and one hour development times. This ELISA offers the convenience of a fast assay while maintaining sensitivity.

NOTE: Due to an approximate 15% cross-reactivity with dexamethasone, this kit may not be suitable for use with samples that contain high concentrations of dexamethasone, such as those collected during a dexamethasone suppression test.

Needed but not supplied: Please download the kit booklet to verify if UltraPure Water (Milli-Q or equivalent) or any other components are needed for this assay.
