Immunogen Recombinant Human Cdk7
Clone MO-1
Isotype IgG2b
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name Cdk7
Background Cyclins and cyclin-dependent kinases (Cdks) are subunits of cell cycle dependent protein kinases that regulate key events during the cell cycle. For orderly progression to take place, Cdks must become fully active only at appropriate times in the cell cycle, and only in appropriate subcellular locations. For example, Cdk2 is activated during the S and G2 phases of the cell cycle and is associated with cyclins A and E. The monomeric form of Cdk2 is inactive as a kinase, its conformation has multiple steric impediments to catalysis. Activation occurs in two steps, and is accompanied by conformational changes that remove the steric hindrances. The first step is the binding of a single Cdk2 monomer to a single molecule of cyclin. This allows for some enzymatic activity, but full activation of Cdk2 and all other known Cdks requires phosphorylation of a conserved threonine residue. Cak (for Cdk-activating kinase) has been shown to phosphorylate the threonine residue and activate Cdk2/cyclin complexes. Cak is itself a cyclin/Cdk complex consisting of cyclin H and Cdk7. Cyclin H is the regulatory subunit of the Cak enzyme, whereas Cdk7 is the catalytic subunit. Thus, Cak functions as a regulator of other cyclin/kinase complexes, suggesting that cyclin/kinase cascades may exist. Cdk7 migrates as a single band at a reduced molecular weight of 36-42 kDa. The MO-1 antibody recognizes human Cdk7.5 Recombinant human Cdk7 was used as an immunogen.
Molecular Weight 40 kDa
Research Area Chromatin and Nuclear Signaling, Cell Cycle, Kinases/Phosphatases
Application Notes Applications include western blot analysis (1-2 µg/ml). Other applications not routinely tested include immunoprecipitation (1 µg/ml cells), immunohistochemical staining of frozen tissue sections (1 µg/ml), and indirect immunofluorescence of tissue-cultured cells. The antibody is not recommended for immunohistochemical staining of paraffin-embedded tissue sections. HeLa human cervical carcinoma cells (ATCC CCL-2) or A-431 human epidermal carcinoma cells (ATCC CRL-1555) are suggested as positive immunoprecipitation and western blot controls.
