anti-Cyclin D1 mouse monoclonal, DCS-6, liquid, purified, small

DCS-6 reacts specifically with cyclin D1 protein present predominantly in G1 phase of cell cycle; it does not cross-react with D2 or D3 cyclins (the closest relatives within the cyclin family); DCS-6 is especially useful in tumor diagnosis: it can be used as fast method to identify cases with 11q13 amplifications. Cyclin D1 gene is identical to the BCL-1 and the PRAD-1 oncogene and is part of the chromosome 11q13 amplicon which is amplified in several common tumor types like breast, lung, esophagus, urinary bladder and head and neck carcinoma. Polypeptide reacting: Mr 36 000 polypeptide (cyclin D1 polypeptide of human cells). Reactivity on cultured cell lines: MCF-7, MDA-MB-134 (breast cancer cell lines), UMSC22 (squamous cell carcinoma cell line), U-2-OS (osteosarcoma cell line) RT 112, A 431, HT 29.
