The following cell line specific conditions are provided as a starting point for transfecting wild-type cells with TrueGuide Synthetic gRNA and TrueCut Cas9 Protein v2 using the Neon Transfection System 10 μL Kit. Further optimization of the electroporation or nucleofection conditions may be necessary for best results.
