Dear all, The 561nm laser of the Zeiss710 confocal does not work anymore. I am afraid it needs to be replaced. I will contact Zeiss to have this problem solved. In the meantime, please use another confocal if you require 561nm excitation. cheers, daniel -- ================================================================== Daniel Van Damme Tel:+32 (0) 9 331 39 13 fax:+32 (0)9 3313809 VIB Department of Plant Systems Biology, Ghent University Technologiepark 927, 9052 Gent, BELGIUM dadam@psb.vib-ugent.be http://www.psb.vib-ugent.be ==================================================================
