Abstract
This protocol details steps taken to create KO cell lines in RAW 264.7 cells.
Materials
DMEM (Thermo Fisher Scientific, 11965-092)
FBS (Thermo Fisher Scientific, 16140-071)
Penicillin/Streptomycin (Thermo Fisher Scientific, 15140122)
CellStripper (Corning, 356230)
Synthego CRISPR Gene Knockout V2 Mouse Kits
Lipofectamine CRISPRiMAX (ThermoFisher Scientific, CMAX00003)

Troubleshooting
Day 0
Plate 2.5 x 10^5 RAW 264.7 cells per well in a 6-well dish.
Day 1
Transfect cells using Lipofectamine CRISPRiMAX, gene specific sgRNAs and recombinant Cas9 (Synthego CRISPR Gene Knockout V2).
CRISPRiMAX protocol
In Tube 1 combine Amount62.5 µL Opti-MEM, Amount3.25 µL sgRNA (from 3 uM stock), Amount2.5 µL Cas9 (from 3 uM stock), and Amount2.5 µL Cas9+ then incubate for Duration00:05:00 . In Tube 2 combine Amount62.5 µL Opti-MEM and Amount3.75 µL CRISPRMAX then incubate for Duration00:05:00 . Combine tube 1 and tube 2. Incubate for Duration00:20:00 . Add drop-wise to 1 well containing Amount1.8 mL of media.

Day 3
Change the media.
Daty 4
Plate single cells into 96-well dishes to obtain clonal cell lines. After subculturing, confirm cell lines via immunoblotting
