Invitrogen™ Cortisone Competitive ELISA Kit

Description

The Cortisone ELISA quantitates Cortisone in serum,saliva,urine,plasm,or dried fecal extracts.

Principle of the method

The Cortisone Competitive ELISA research-use-only kit is designed to quantitatively measure cortisone in extracted dried fecal samples,urine,saliva,plasma,and serum samples. This kit measures total cortisone in serum and plasma and in extracted fecal samples. A cortisone standard is provided to generate a standard curve for the assay and all samples should be read off the standard curve. Standards or diluted samples are pipetted into a clear microtiter plate coated with an antibody to capture rabbit antibodies. A cortisone-peroxidase conjugate is added to the standards and samples in the wells. The binding reaction is initiated by the addition of a polyclonal antibody to cortisone to each well. After a two-hour incubation the plate is washed and TMB substrate is added. The substrate reacts with the bound cortisone-peroxidase conjugate to produce a colored product. After a short incubation,the reaction is stopped and the intensity of the generated color is detected in a microtiter plate reader capable of measuring at 450 nm.

Rigorous validation

Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity,specificity,precision,and lot-to-lot consistency. See manual for more information on validation.

Cortisone (Kendall’s Compound E) is a glucocorticoid which is the product of cortisol (Compound F) deactivation by 11-beta-HSD2 (hydroxysteroid dehydrogenase), prohibiting receptor activation. The balance between cortisone and cortisol glucocorticoids helps to regulate the anti-inflammatory response. Cortisone is identical across all species.
