Anti-CDK4, CT (CDK4, Cyclin-dependent kinase 4, Cell division protein kinase 4, PSK-J3)

CDK4 is a member of the Ser/Thr protein kinase family. This protein is highly similar to the gene products of S. cerevisiae cdc28 and S. pombe cdc2. It is a catalytic subunit of the protein kinase complex that is important for cell cycle G1 phase progression. The activity of this kinase is restricted to the G1-S phase, which is controlled by the regulatory subunits D-type cyclins and CDK inhibitor p16(INK4a). This kinase was shown to be responsible for the phosphorylation of retinoblastoma gene product (Rb). Mutations in this gene as well as in its related proteins including D-type cyclins, p16(INK4a) and Rb were all found to be associated with tumorigenesis of a variety of cancers. Multiple polyadenylation sites of the gene have been reported. Applications: Suitable for use in Immunofluorescence, Western Blot, Immunohistochemistry, Flow Cytometry and ELISA. Other applications have not been tested. Recommended Dilution: Western Blot: 1:1000, Immunohistochemistry (FFPE): 1:50-1:100, Flow Cytometry: 1:10-1:50, Immunofluorescence: 1:10-1:50, Optimal dilutions to be determined by the researcher.
