Assay Principle
The Tribo™ Human Carcinoembryonic Antigen ELISA Kit is designed for in vitro quantitative determination of CarcinoEmbryonic Antigen (CEA) concentrations in human serum and plasma samples. This assay employs an antibody specific for Human Carcino Embryonic Antigen CEA coated on a 96-well plate. Standards and samples are pipetted into the wells and Carcino Embryonic Antigen CEA present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Carcino Embryonic Antigen CEA antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Carcino Embryonic Antigen CEA bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450nm. The concentration of CEA in the samples is calculated opposite to the standard curve.
Applications: Direct Assays: quantitative CEA in different tissues.
Key Features: Sensitivity: The minimum detectable dose of human CEA is typically less than 2.0 pg/mL.
Tribo™ Human CEA ELISA Kit is a Solid-phase sandwich ELISA for the quantitative determination of CEA. The microplate is pre-coated with a capture antibody specific to the target. Target present in the sample or standard binds the immobilized antibody, is detected with a biotinylated detection antibody and streptavidin-HRP, and quantified colorimetrically against a standard curve.
Kit Components
The kit provides a pre-coated microplate, target standard for standard-curve generation, detection reagents (detection antibody and enzyme conjugate), wash buffer, substrate, and stop solution. Refer to the product datasheet for the complete component list and quantities.

Safety & Handling
This kit is validated for serum, plasma. Other matrices may require additional in-lab validation.
This assay has a sensitivity of < 2.0 pg/mL. Samples reading outside the range should be diluted or concentrated.
The kit provides a pre-coated microplate, target standard for standard-curve generation, detection reagents (detection antibody and enzyme conjugate), wash buffer, substrate, and stop solution. See the datasheet for the full component list and quantities.
A standard microplate reader capable of measuring absorbance at 450 nm is required for this sandwich ELISA.
