I fix cells expressing S65T GFP by addition of 1/20th volume formalin (the
cheap liquid, just replace your stock soln every 6-12 months) directly to
the culture media (~1.8%) for 5 minutes at RT. Followed by centrifugation
for 5 min cells are resuspended in excess volume 1 x PBS and stored at 4
C. An increase in fluorescence can often be observed as more GFP can fold
at 4 C O/N. These cells can then be stained with DAPI for cell-cycle or
with Ab for a second label.
