Library Details

  • Species
  • Genes targeted
  • gRNAs
  • Controls
    98 (49 essential genes, 49 nonessential genes)
  • Lentiviral Generation

Library Shipping

This library is delivered as suspended DNA in a microcentrifuge tube on blue ice. The tube's contents will not necessarily be frozen. For best results, minimize freeze-thaws.

  • Volume
    ∼20 µL
  • Concentration
    50 ng/µL

Depositor Comments

See the TKO protocol from the Moffat Lab (document linked above) for details on library amplification, viral packaging, transduction, screening, sequencing, and analysis, including LCV2 primers for amplification. The depositing lab recommends using DrugZ to identify synergistic or suppressor chemical genetic interactions and BAGEL to analyze fold changes and identify essential or non-essential genes.
