Product Description

The CDK Antbody Sampler Kit provides and economical means of evaluating Cdk proteins. The kit contains enough primary and secondary antibodies to perform four western blot experiments.


Specificity / Sensitivity

Each antibody in the CDK Antibody Sampler Kit detects endogenous levels of its respective target protein and does not cross-react with other family members.


Source / Purification

Monoclonal antibody is produced by immunizing animals with a recombinant human cdc2 fusion protein, synthetic peptides corresponding to residues of human CDK2 and recombinant human CDK7, and residues near the carboxy terminus of human CDK4, human CDK6, and human CDK9 proteins.

Cyclin-dependent kinases (CDKs) are the core effectors of cell cycle progression. CDK activity is regulated through association with their cyclin partners and cyclin-dependent kinase inhibitors (CKIs) as well as by activating and inhibitory phosphorylation events. Inhibition is mediated by Wee1 and Myt1 kinases that target residues at the amino terminus of CDK1 (1,2). Dephosphorylation of these residues by cdc25 phosphatase leads to activation of CDK kinase activity (3). The CDK7/cyclinH complex is the ubiquitous mammalian CDK-activating kinase (CAK) that phosphorylates a conserved threonine residue in the T-loop domain of CDKs. The carboxy-terminal domain of RNA polymerase II is also a target of CAK as well as CDK9/cyclinT (4,5). CDK4/6 associate with cyclinD and phosphorylate retinoblastoma protein and initiate progression through the restriction point in G1 (6). CDK2 associates with cyclinE in early S phase and cyclinA later in G2. CDK1/cyclinB regulates the initiation of mitotic events (7).
