Intra-assay Precision (Precision within an assay): CV%<15% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
Inter-assay Precision (Precision between assays): CV%<20% | ||||||
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 human CA15-3 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 an anti-human CA15-3 antibody.
Five vials standard (0.5 ml/bottle)--- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
One vial HRP-conjugated CA15-3 antibody (6 ml/bottle) --- Bind to the CEA in the samples or standards and react with the substrate to make the solution chromogenic.
One vial Sample Diluent (11ml/bottle) ---Dilute the sample solution.
One vial Wash Buffer (20x concentrate) (15 ml/bottle) --- Wash away unbound or free substances.
One vial Substrate A (7ml/bottle) --- Mix with substrate B and then interact with TMB to elicit a chromogenic reaction.
A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at603 nm or 630 nm.
An incubator can provide stable incubation conditions up to 37°C±5°C.
