Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
Inter-assay Precision (Precision between assays): CV%<10% | ||||||
Three samples of known concentration were tested in twenty assays to assess. |
To assess the linearity of the assay, samples were spiked with high concentrations of mouse CORT in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||

A micro ELISA plate --- The 96-well plate has been pre-coated with goat anti-rabbit CORT antibody.
Six vials lyophilized standard (0.5 ml/bottle) --- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
Anti-mouse CORT Antibody (1 x 6 ml) --- Act as the detection antibody.
HRP-conjugate (1 x 6 ml) --- HRP catalyzes TMB substrate to elicit a chromogenic reaction.
Wash Buffer (20 x concentrate) (1 x 15 ml) --- Wash away unbound or free substances.
Substrate A (1 x 7 ml) --- Mix with substrate B, and the TMB is catalyzed by HRP to elicit a chromogenic signal.
A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 600 nm to 630 nm.
An incubator that can provide stable incubation conditions up to 37°C±5°C.
Centrifuge
Vortex
Squirt bottle, manifold dispenser, or automated microplate washer
Absorbent paper for blotting the microtiter plate
