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 va
Each vial contains 100 ul 1 mg/ml purified antibody in PBS containing 0.09% sodium azide.
Source:
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.
Application Notes:
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.
