Hello ,

I established a stable cell line expressing GFP tagged to a centrosomal gene having G418 drug selection marker. I validated the stable line by IFA and Western blotting, results are fine. I am maintaining them on G418 containing media. However for first 5 passages the GFP expression is stable after that there is a reduced GFP expression. How can I retain the GFP expression for more passages? How to resolve this problem?

Thanks!
