Anti-CDKN1B

p27 KIP 1 is a cell cycle regulatory mitotic inhibitor of cdk activity. p27 KIP 1 is a candidate tumor suppressor gene, and has been proposed to function as a possible mediator of TGF beta induced G1 arrest. p27 KIP 1 is up regulated in response to antimitogenic stimuli. The increased protein expression of p27 results in cellular arrest by binding to cyclin/Cdk complexes such as cyclin D1/Cdk4. Decreased levels of p27Kip1, mainly due to proteosomal degradation, are found in various epithelial tumors originating from lung, breast, colon, ovary, esophagus, thyroid and prostate.Tissue specificity: Expressed in all tissues tested. Highest levels in skeletal muscle, lowest in liver and kidney. Applications: Western Bloting: 1:500-1:2000., ELISA: Suggested dilution 1:10000., Optimal dilutions to be determined by the researcher.
