Confirming the specificity of the dominant negative-like effect of ΔF-CFTR on WT-CFTR in native IB3-1 CF bronchial epithelial cells. A. Similar co-expression biochemical experiments with G551D-CFTR and WT-CFTR. B. Increasing amounts of ΔF-CFTR do not affect the maturation and processing of a different glycosylated membrane protein, the purinergic receptor channel, P2X4.
