Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...

Instability of the electrode (i.e. protein instability), inhibition of an enzyme at high substrate concentration, or electrode passivation are all possible.

prof V.S Muralidharan

in CV what you measure is the net current flow at a particular potential depending upon the sweep rate-

if you do the same experiment at the same sweep rate galvanostatically you may get the same current
