It would be better if you dilute the virus in serum free DMEM instead of PBS too


I thought DMEM doesn't let virus attach to host cell surface/receptors, and that is why we wash the cells before adding virus+PBS.


DMEM is just a salt solution like PBS ....its the FBS that can inhibit attachment. You wash the cells to remove the serum.

Thanks, I did as you said today. I have to wait for some days now.
