GFP fluorescence quenching

It is well established that GFP fluorescence is quenched in the acidic environment of the lysosome. However, does anyone know if this is the case as well in fixed cells? Would the fixation method influence this (methanol vs formaldehyde)?
Thank you

    Longer fixation time with formalin say 30 min reduces fluorescence.

    Little girls like to be seen in the best clothes from a young age, and as a parent you have the choice on how you dress them. There are some http://www.urbaniana.edu/it/louisvuittonhandbgs.aspx lovely clothes for toddler girls, especially the cute dresses. But do not stop at dresses as your toddler can still look fashionable and trendy in jeans, tees, leggings, shorts and much more.
