Dear All,
I am doing one-step reverse transcription PCR in droplet, which is based on TaqMan probe. About half a year ago, everything works well. But recenly, the ddPCR starts generating some odd result , in which bright spot occurs in every single droplet. It seems to be something aggregating within the droplet. I post the figure as the following. Could anyone please give me some suggestions on why this happens and how I can solve this problem?
