Intro

The Functional Genomics Platform at Whitehead Institute provides advice and reagents to researchers interested in implementing large-scale CRISPR/Cas9 screens in mammalian cells.

We use the CRISPR/Cas9 system to identify modulators of different cellular phenotypes, such as viability and the output of reporter systems.

The FGP is directed by Heather Keys, Ph.D.

Jonathan Weissman, Ph.D. is the faculty advisor for the FGP.

On this website, you can find more details about our work, our team, contact information, and protocols.

Work

We assist researchers at all stages of the screening process, including planning, implementation and validation of genetic screens:

  • Experimental design
  • sgRNA library design and propagation
  • Virus preparation for optimization and screening
  • Vector design
  • Sequencing library preparation
  • Data analysis
  • Follow-up strategies
