Compound Testing Services

AssayQuant's compound testing services provide the flexibility to meet your needs, including a variety of compound potency measurements and the option for preincubations, comparison of ATP at the Km app or 1 mM, and analysis with recombinant enzyme or crude cell lysates.

We offer rapid turnaround at seven (7) business days for most determinations, including potency, mechanism of action or residence time and 14 business days for large panel kinome profiling.

Introducing profiling services for phosphatases & lipid (DGK) kinases! Please contact us to learn more.

PhosphoSens enables complex determinations to provide critical understanding of enzyme inhibitor properties to improve drug performance, including:

  • Kinome Profiling – 1 or more concentrations & up to 377 Protein Kinase targets (410 assays w/mutants; new assays added continuously).
  • IC50 or K–  12 pts, BSA or DTT; low or high ATP, protein complexes & crude lysates
  • kinact/KI  – 24 pts for time-dependent inhibition with covalent compounds
  • Residence Time – Uses Jump Dilution method with a range of detection from 30 seconds to 2 days
  • Mechanism of Action (MOA) – ATP & peptide or lipid substrates
  • EC50 – Assess potency of compounds for target activation

Examples of Enzyme Inhibitor Assessments Offered as Custom Service

Enzyme Inhibitor Assessments

D. IC50 vs kinact/KI Plots

ic50-vs-kinact-ki-plots-1

13 inhibitors with IC50 values in a 3.4-fold range (1.6 - 5.5nM) are differentiated with kinact/KI.

E. Residence Time

residence-time-1
residence-time-hours

Jump-dilution method for determination of Residence Time (Tau) for receptor or soluble tyrosine kinases with values ranging from 8.3 min (0/14h) to 1,149 (19.2 h). Due to the high precision of the platform, can detect values from 30 sec to 2 days.

D. KinSight Kinome Profiling With a Panel of 400+ Wild-Type Kinases Providing Kinetic Insights into Selectivity and Mechanism of Action
