Most polyclonal CEA antisera show cross-reactivity with related antigens such as biliary glycoprotein (BGP) and non-specific cross-reacting antigen 1/11 (NCA). PARLAM 4 does not show cross reactivity, neither with BGP nor with NCA. In immunoblotting the antibody recognizes a single band of 180 kD.

Each vial contains 100 ug 1 mg/ml purified antibody in PBS + 0.09% sodium azide.

Store at 4 degree C, or in small aliquots at -20 degree C.

PARLAM 4 is useful for flow cytometry, immunoblotting, immunocytochemistry on methanol fixed cells and immunohistochemistry on frozen tissues when using a PBS buffer containing 0.1 mM CaCl2 and 0.1 mM MgCl2. The antibody is also reactive in formalin-fixed and paraffin-embedded tissue sections after treatment with citRate buffer pH 6.0 in an autoclave. Human colon carcinoma tissue is used as positive control. Optimal antibody dilution should be determined by titRation; we recommend a 1:25 - 1:100 dilution for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 - 1:500 for immunoblotting appliCation.

Source Note: PARLAM 4 is a Mouse monoclonal IgG1 antibody derived by fusion of Sp 2/0 Ag 14 Mouse myeloma cells with spleen cells from a BABL/c Mouse immunized with isolated Human CEA. The immunogen has been isolated from Human colonic carcinoma cells.

Tumour marker, Cancer, Cell differentiation

This monoclonal antibody is reactive with Human carcinoembryonic antigen (CEA), a tumour associated antigen with oncofetal characteristics. Although CEA can be found in tissues of non-neoplastic diseases and normal epithelia, it occurs also in a large variety of carcinomas. Therefore, immunohistochemical detection of CEA is frequently used for the histopathological diagnosis of Human tumours.
