Rapid data turnaround

Rapid, reliable data turnaround is essential for keeping programs on track, on time and on budget. Standard data turnaround for study requests is 10 business days from compound receipt, with 5 business day turnaround available for regularly scheduled ongoing screening programs and subscription services. Average data turnaround is eight business days.
 

Data Turnaround
Study Report Data turnaround
Average data turnaround for 2009 - 2010 calendar years was 8.0 days. Ninety percent of study reports were delivered within ten business days of compound receipt at KINOMEscan. Large projects such as compound library profiling, and single target high-throughput screening may vary depending on scale.


Accurate, precise & reproducible data

KINOMEscan screening partners have long recognized that accurate, precise and reproducible kinase profiling data are critical components of the discovery and development process and are the cornerstone of a successful screening partnership. All KINOMEscan assays undergo thorough validation prior to being released into production and assay performance is continually monitored to ensure data consistency & longitudinal concordance.
  • Data accuracy and precision have been demonstrated in several peer-reviewed publications from both the KINOMEscan team and our partners.


Assay quality: Primary screen reproducibility

  • Outstanding screen to screen reproducibility
  • Enables data to be interpreted with confidence


Data Consistency
Profiling of the indicated compounds at 10uM in fourteen independent experiments against 442 kinases over a one year period. Correlation analysis was performed in a pair-wise comparison to calculate the correlation coefficient. The correlation coefficients range from 0.91 to 0.97 with an average of 0.95 [click graph to enlarge].


Assay quality: Z’ values

  • Z’ values measure assay noise and predictive value
  • High Z’ values reproducibly measured across entire assay panel
  • High Z’ values ensure low false positive/negative rates


Assay Quality
Average Z' values and standard deviations were calculated for each kinase based on fourteen control wells per experiment in over 135 independent experiments spanning a period of sixteen months. Average Z' = 0.71 [click graph to enlarge].




Detect multiple types of kinase inhibitors

Although the majority of kinase inhibitors developed so far have been type I or type II inhibitors that fully or partially overlap the ATP binding site, there are also examples of non-ATP competitive “allosteric” inhibitors that target the kinase active site and inhibit catalysis by repositioning key catalytic residues. Allosteric inhibition may represent a promising strategy for the development of highly potent & selective compounds. KINOMEscan affords investigators a flexible screening solution for detecting these multiple inhibitor types and to thereby extract the maximum value from their chemical assets. To learn more about the types of allosteric inhibitors detected in KINOMEscan assays, visit our Allosteric Inhibitor page.


Detection of Type I, II & Allosteric Inhibitors
Binding constant (Kd) determinations were measured for interactions between gefitinib, a known Type I inhibitor and EGFR (Kd = 3.4nM); imatinib, a known Type II inhibitor and KIT (Kd = 7.5nM); and CI-104, a known non-ATP-competitive inhibitor and MEK1 (Kd = 120nM). These data illustrate the diversity of inhibitor types detected in KINOMEscan assays [click graph to enlarge].

Large dynamic range for accurate affinity measurements

KINOMEscan binding assays use low kinase concentrations (less than 0.1 nM). This feature, coupled with quantitative, precise and ultra-sensitive qPCR readout, affords a large dynamic range (greater than five logs) for the measurement of accurate affinity values (Kd less than 100 pM to greater than 10 uM). These features provide a flexible, sensitive and highly quantitative platform for the identification and discrimination of a wide spectrum of inhibitors.
 

Assay Sensitivity
Binding constant (Kd) determinations for the indicated compounds against LOK demonstrate the broad range (> 5 logs) of interaction affinities quantitatively measured using the KINOMEscan assay platform.  Assays are performed at low kinase concentrations (<0.1 nM), which enables the measurement of accurate Kd values in the pM range [click graph to enlarge].
