Biological Information
Background Information:
Members of the cyclin-dependent kinase pair CDK9/cyclinT1, also called positive transcription elongation factor b (P-TEFb), facilitates the transition from abortive to production elongation by phosphorylating the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAP II), SUPT5H and RDBP.

Testing Information
Procedure Summary:
CDK9/cyclinT1 (h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 100 µM KTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC, 10 mM MgAcetate and [gamma-33P]-ATP (specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ATP mix. After incubation for 40 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting.
Substrate:
100 µM KTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC
Tracer:
33P
ATP Concentration:
[ATP]= 45µM (Km= 30.9µM )
Incubation:
40 min at Room temperature
Control Inhibitor:
Staurosporine
Test Sample Requirements:
Please provide compounds dissolved in 100% DMSO (PBS or HBSS prohibited).
Stock solution should be ≥50× the final assay concentration (a 10 mM stock is also acceptable).
Required volume:
– <60 kinase assays: 120 µL of 50× stock
– ≥60 assays: 420 µL of 50× stock
If you supply 10 mM stocks or powder (pre-weighed), we will apply the appropriate conversion.
For batches of ~50 compounds supplied as solids, the TAT will be extended.
