Hi Jeroen, We used a BioRad iCycler iQ for the measurements in Thermofluor-based high-throughput stability optimization of proteins for structural studies. Ericsson, et. al. Analytical Biochemistry (2006) 357:289-298. The wavelengths for excitation and detection were ~490 and ~575 nm,

Hi Jeroen, I assume you are planning to use Sypro Orange. We are using the Roche LC480 (simply because it's around in the lab next door) and it does the job although it's a little inconvenient to tweak the settings. Many people use the iCycler from Biorad. This machine is a little more

Sorry for the off-topic but can somebody recommend highly a sensitive RT-PCR machine for the thermofluor experiment (sypro orange). That would imply excitation below 500 nm (ideally 470) and detection at about 570 nm, right? I know several simple machines have a problem with the 570 nm...
