High Throughput Screening
High throughput screening is
available to academic and corporate research laboratories. The MHTSC staff will
work with clients to implement HTS assays. Modifications often required include
optimizing buffer choice and concentration, target protein and substrate or
ligand concentrations, tolerance to DMSO, temperature, pH, and/or ionic strength,
divalent cation concentrations and incubation times of the reaction. Additional
factors that usually need to be addressed before beginning HTS include:
assessment and
enhancement of target molecule and substrate or ligand stability under
screening conditions; and optimization of signal above background. Modifications
to an assay can be made to accommodate absorbance, radio-isotopic,
fluorometric, luminescent, or other means of detection.
We offer screening to
clients at different levels or stages. In addition to full screens from our
library of 100,000 compounds, a smaller scale screen may be conducted with a subset
of our compound library (~10,000 compounds). The compounds selected for this purpose will include a diverse
and representative set of the larger compound collection. After the initial assay
(conducted at a single concentration), active compounds are retested to verify
activity. Verified active compounds are evaluated in a dose response assay to
help prioritize the active compounds. Evaluation of each compound’s activity in
a dose response allows discrimination of potency and mechanism and assists in
structure-activity relationships.
