SLAS2019 Short Courses

Establishing Cell-Based Assays for Screening

This course will describe developing standard procedures for handling cultured cells to set up cell-based assays including techniques for measuring cell health and the pathways leading to cytotoxicity, validation of in vitro assays applied to 3D model systems, cell line authentication as a component of assay reproducibility, developing siRNA screening assays, using CRISPR technology as a validation step, and an overview of various GPCR screening methods.

Who Should Attend:

  • Assay development scientists interested in establishing reproducible cell-based assays
  • Scientists seeking an overview of methods to confirm health and functionality of cells used in combination with other screening assays
  • Screeners interested in design and implementation of siRNA assays and CRISPR technology to identify novel targets
  • Screeners interested in an overview of state of the art methods for screening GPCR targets

How You Will Benefit From This Course:

  • Participants will receive an overview of potential pitfalls to consider during design of cell-based assays.
  • The advantages and disadvantages of HTS-compatible assays for measuring cell viability & apoptosis will be presented along with descriptions of multiplexing assays for measuring cell stress response pathways.
  • Factors to consider when selecting off-the-shelf in vitro assays applied to 3D culture models.
  • Participants will receive copies of presentations and benefit from the opportunity to interact with experts in designing and implementing siRNA and GPCR screening assays.

Course Topics:

  • Cell culture techniques specific to characterizing high throughput screening assays
  • Overview of various cytotoxicity assays, methods for multiplexing as an internal control, and measuring cell stress responses with biochemical and genetic reporter assays
  • Description of techniques for design and implementation of siRNA screening assays
  • Overview of creating, miniaturizing, and detection methods used for GPCR assays

Geoffrey Bartholomeusz

Geoffrey Bartholomeusz
UT MD Anderson Cancer Center

Dr. Geoffrey Bartholomeusz (Ph.D.) is an associate professor and Director of the Target Identification and Validation Program at the UT M.D.Anderson cancer center, Houston Texas. Dr. Bartholomeusz research is focused on developing preclinical in-vitro 3D models for target identification and validation. These models include multicellular tumor spheroid models, 3D co-culture models and PDX tumor-derived ex-vivo tumor tissue models. These 3D models systems are used as platforms for high throughput siRNA and small molecular screens with a goal to improve our ability to identify novel targets for the development of effective therapies for cancer. CRISPR technology is applied as a validation step to confirm the role of the identified target in either cancer biology or as a potential target for drug development. Dr. Bartholomeusz is well published in the field of cancer biology and treatment.
