I have transfected neurons using electroporation before playing plasmid with Cas9 which makes a single double stranded cut. But I am not able to see any results. Is there a way I can delete the whole gene using CRISPR in primary neuron culture?
Primary neurons are very difficult to transfect, and electroporation likely damages the neurons; you can try to package your Cas9 into a lentiviral vector; another approach, if you purchase the knockout mouse with your target gene (if it exists), you can isolate primary neurons from its brain with knockout already present.
