Cystic fibrosis transmembrane conductance regulator gene (CFTR) shows a complex mechanism of tissue-specific and temporal regulation. CFTR mRNA detection and measurement are extremely difficult because of the low to very low levels of its endogenous expression. In this paper, we describe four different non-PCR methods optimized to analyze CFTR transcripts in epithelial cell lines, primary cell lines and native tissues that express significant amounts of CFTR transcript.
