is there any nuclear localization signal which will retain EGFP in the nucleus of the N2A cells?
you can use this NLS as a fusion with eGFP - PAAKRVKLD

depending on where you add it (N or C terminal) you will have to add start or stop codon of course.
It might also help to add multiple NLS if you don't get sufficient nuclear localization.
Thank you for your answer! I will try this sequence.
I am looking for journals that admit the publication of results from applying the IUCN Standard for designing and monitoring Nature-based solutions. Many thanks for considering my request.
