Hello, I recently ran an assay using Thermo fisher Hot Start 2x master mix and Actb primers from this set: http://realtimeprimers.com/rat-housekeeping-gene-primer-set.html . I am using a Roche LightCycler 96 on the FAM setting and did not get back any curves or Ct values. I think I have set up the assay wrong so that no fluorescence was detected. Do I need to add SybrGreen or another fluorescent reporter? Can I add that to my master mix seperately so I don't have to buy new master mix?
