Product Overview
This rabbit polyclonal antibody targets cyclin-dependent kinase 7 (gene CDK7) in human samples and is validated for Western blot. The predicted molecular weight is 39.0 kDa, and the supplier reports an observed band at about 39 kDa.
CDK7 is the kinase at the core of the CDK-activating kinase (CAK), which it forms with cyclin H and MAT1. It activates other CDKs such as CDK1 and CDK2 by phosphorylating their T-loop, and as part of the general transcription factor TFIIH it phosphorylates RNA polymerase II, linking cell cycle control to transcription.

|---|
Samples with a confirmed band (WB): MCF-7 cells, HeLa cells, A549 cells, HepG2 cells, 293T cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant human Cdk7 fragment (Asp31–Phe346), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 94.9% and 96.1%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places cyclin-dependent kinase 7 in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
