it works ! At least in Burkitt+s lymphoma cell lines, which are of B-cell
origin. I+ve established cell lines stably transfected with a high- and
low-expressing gfp-construct 6 weeks ago, they grew out quite esily (nice to
follow them growing on a 96 well plate by the way) and are still living happily
with almost no change in brightness of gfp-fluorescence. So at least these cells
have found a way to deal with gfp-turnover and degradation (some of the cells
actually didnt so they turned into big green blastoid-like cells). This work has
not been published yet, so you surely dont find it the literature.
Hope this helps !
