The High Throughput Screening (HTS) Core facility offers the following major services:
  1. Screening of small or large chemical libraries using a fully automated HTS system. The service uses biochemical assays in vitro molecularly targeted.
  2. Cell-based assays. The service includes in-house NCI-60 cell line screen using a low throughput screening system, custom-made cell-based assays and High Content screening using ImageXpress Ultra.
  3. Lead characterization. Kinase profiling services are available using PamChip 4 microarrays and PamGene Station12. In the system, 144 Tyr or 144 Ser/Thr kinase peptide substrates containing 4 positive control ones are used for the kinase reaction.
Discussing with investigators the various approaches in identifying/screening compounds
Assay Development
Assisting investigators in developing new assays or adapting their low throughput assays into automated, high throughput screening formats. Assays may involve proteins, cell lines, or simple model organisms.
Assay Implementation
The core subjects the assays to high throughput screening and analyzes the results to identify active hits for each assay.
Data Analysis
Performing structure-activity relationship (SAR) analysis of compounds demonstrating activity in the individual assays.
Data Integration and Management
The core assists in collecting, maintaining and interpreting data for project investigators.
Drug Discovery: A Team Approach
Drug discovery is a multi-disciplinary effort. In order to advance a project efficiently, it is important that everyone involved be up-to-date with the progress of the project such as the latest hits/leads. It is also crucial to form a consensus about the characteristics of the compounds, e.g. potency, selectivity, etc., so that the team can effectively decide whether to go further with a particular compound and/or its derivatives. The HTS Core services provide an effective framework for the project team members to interact.
The Core Advisory Committee represents the broad spectrum of expertise required for the successful operation of the HTS Core. This committee reviews all submitted proposals and ranks them based on their scientific merits and feasibility. Priorities are assigned to each proposal, and core staff members carry out the experiments accordingly. Highest priority is given to cancer center members with peer-reviewed funding.
