This antibody portfolio includes a wide range of tissue- & tumor-specific primary antibodies for basic research, product development and analysis of a variety of biological questions. The monoclonal antibodies are perfectly applicable for all cell or tissue biology studies and for the analysis of predictive markers in research. High epitope affinity Highly specific detection of the target protein Unconjugated Suitable for e.g. western blot, immunoprecipitation, ELISA & immunofluorescence anti-Cyclin-Dependent Kinase 4 mouse monoclonal, DCS-156 50 μg/ml, monoclonal, affinity purified DCS-156 reacts specifically with cdk4 protein present predominantly in G1 phase of cell cycle; it does not cross-react with cyclins. In immunohistochemical application on frozen sections of head and neck carcinoma (oropharynx and hypopharynx carcinoma) and cervix DCS-156 shows distinct nuclear staining, especially in tumor areas of enhanced proliferation. Epitope recognized: aa 270-290. Application Western Blot (WB): 1:50-1:500 (0.1-1 μg/ml) Western blot analysis of human HeLa cell lysate with anti-Cyclin-Dependent Kinase 4 antibody. Western blot analysis was performed on either 5 μg or 10 μg of HeLa lysate. Cells were lysed in PBS by homogenization. The PVDF membrane was blocked with 5% dry milk in PBST for 1 h at RT. The primary antibody anti-Cyclin-Dependent Kinase 4 mouse monoclonal, DCS-156 (Cat. No. 690096) was diluted in blocking buffer (antibody concentration 0.5 μg/ml) and incubated for 1 h at RT. The secondary antibody goat anti-mouse IgG polyclonal, HRP conjugate was also diluted in blocking buffer (antibody concentration 0.2 μg/ml) and incubated for 1 h at RT. The bands were visualized by chemiluminescent detection using Pierce™ ECL Western Blotting Substrate. Not a medical device / Not an IVD product
