Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Comment:

Sequence similarities: Belongs to the immunoglobulin superfamily. CEA family.

Tissue Specificity: Found in adenocarcinomas of endodermally derived digestive system epithelium and fetal colon.

Plate: Pre-coated

Protocol: human CEA ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CEA has been precoated onto 96-well plates. Standards(NSO, K35-A685) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CEA is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CEA amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 20000pg/mL, 10000pg/mL, 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 312pg/mL human CEA standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum or plasma( heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each human CEA standard solution and each sample be measured in duplicate.

Assay Precision:

Background:

Protein Function: Cell surface glycoprotein that plays a role in cell adhesion and in intracellular signaling. Receptor for E.coli Dr adhesins. .

Background: Carcinoembryonic antigen(CEA) is a complex immunoreactive glycoprotein with a molecular weight of 180,000 comprising 60 % carbohydrate. It is found in adenocarcinomas of endodermally derived digestive system epithelia and in fetal colon.Carcinoembryonic antigen is one of the most widely used tumor markers in serum immunoassay determinations of carcinoma.
