HEA125, Epithelium-specific Glycoprotein, Egp34, EpCAM (CD326)Catalog number: HE500
The antibody HEA 125 reacts intensely with all carcinoma derived from the intestinal tract, stomach, pancreas, liver, lung, breast, ovary, thyroid gland, kidney, bladder, prostate and metastases thereof. Stratified squamous epithelia usually stain less intensely then adenocarcinoma. The antibody is suitable for differentiation between carcinoma an non-carcinoma. Keratinizing areas of a tumour mass usually remain unstained as sarcoma, lymphoma, melanoma and neurogenic tumours do. Epithelial cells express a number of characteristic proteins and glycoproteins like cytokeratins, epithelial membrane antigen and epithelium-specific glycoprotein Egp34 (HEA125). The monoclonal antibody HEA125 which has been derived from immunisation of mice with a colon carcinoma cell line shows a broad reactivity pattern. It is labelling most human epithelial cells and epithelium derived tumours. It doesn't react with epidermal keratinocytes, parietal cells, hepatocytes, thymus cortical epithelium, myoepithelia, and non-epithelial tissues. 34 kDa Epithelium-specific membrane glycoprotein HEA 125.
Immunogen: Living human colon carcinoma cell line HT-29
Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide** and BSA. The volume is sufficient for at least 50 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art. No. PU002, if further dilution is required.
