Retention factor (k) is simply the additional time that the analyte takes to elute from the column relative to an unretained or excluded analyte that does not interact with the stationary phase and which, by definition, has a k value of 0. Thus

Most common CFTR mutation is a ΔF508 -

Prevents normal transport of CFTR to the plasma membrane by blocking its packaging into COPII vesicles budding from the ER. 

Change the conformation of the cytosolic portion of CFTR so that the signal is unable to bind to Sec24.

In electrophoresis because of the varying charges and masses, of different molecules

and particles of a mixture will migrate at different velocities under uniform force and

will thus be separated into single fractions.
