Cortisol ELISAs

Cayman Chemical offers two excellent cortisol ELISA kits for the accurate measurement of cortisol in urine, plasma and other sample matrices.The cortisol ELISA has a detection range of 6.6-4,000 pg/ml and sensitivity (80 percent B/B0) of ~35 pg/ml whilst the cortisol Express ELISA can measure cortisol levels down to 110 pg/ml in less than four hours. Requiring only 50 ul sample volume, the cortisol ELISA and cortisol Express ELISA contain an exclusive patented highly stable acetyl cholinesterase (AChE) tracer. AChE has a wide pH range, is highly resistant to interference from common buffer salts and preservatives and requires no 'stop' reagent enabling the plate to be read when convenient and does not self-inactivate during turnover.

Benefits of using these cortisol ELISAs
• Only 50 µl sample volume needed
• Low limit of detection
• Compatible with urine, plasma and faeces
• Highly stable AChE tracer with wide pH range
• Requires no 'stop' reagent so can be read when appropriate
• AChE does not self-inactivate during turnover enabling re-development if splashed or spilled

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