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.

 Scatchard plots are based on repeated equilibrium dialyses with a constant concentration of antibody and varying concentration of ligand. 
If all antibodies have the same affinity, then a Scatchard plot yields a straight line with a slope of Ka. The x intercept is n, the valency of the antibody, which is 2 for IgG and other divalent Igs. For IgM, which is pentameric, n  10, and for dimeric IgA, n  4. In this graph, antibody #1 has a higher affinity than antibody #2.
