I am currently involved in project that need to transfect B cell with siRNA via NUCLEOFECTION ,problem is viability varies 80 to 16 percent.dose any one faced same problem ,if yes please let me know how to solve it ...thanks
I use it quite regularly and what I do is the following: the day after, when I change the medium, I only remove half of it and put half of fresh one. I think it is good for the cells to keep some released growth factors.
Of course I guess you have already set up a series of parameters (voltage, duration of the pulse, cell density etc).
