Both were comparatively stable & bright, even when using STED microscopy. (Still no comparison to FPs in the green, though.) mKate2 and Tag-RFP worked quite well, too. Sorry that is all I can contribute! Nicolai >>>>>>>>>><<<<<<<<>>>>>>>>>><<<<<<<<<<>>>>>>>>>><<<<<<<<<< Dr. Nicolai T.

Many thanks in advance for your help and very best regards, Laurent.
