Hi everyone,
I'm currently working on the HaCaT keratinocyte cell line.
I have them in culture under low and high calcium concentration to keep them undifferenciated or differenciated, respectively.
I have trouble having consistent transfection efficiency with turbofect reagent.
My replicate vary bbetween a few % of GFP postive cells to one time 60%.
I don't seem to be able to pinpoint the cell culture or transfection specs given such varying outcomes.
I was wondering if preparing my vector/turbofect mix in low calcium medium could dampen downstream transfection efficiency ?
Any advice ?
