Notebook Flow Cytometry

  • All cells for flow cytometry were transfected with the promoter of interest in front of GFP and the reference plasmid with JeT and mCherry in a 2:1 ratio. This ratio was chosen to ensure that we have GFP in every cell expressing mCherry and thereby increasing the number of double positive cells.
  • Time course measurement of 24 and 96 well plate: Triplicates of cells transfected with the same promoter were loaded at different positions of the plates (Figure ?) to ensure that the results do not change significantly over the time course of one flow cytometry measruement.
