Representative electrophoreograms of <i>CFTR</i> SNaPshot multiplex assay.

<p>a) Electrophoreogram of <i>CFTR</i> SNaPshot multiplex assay for detection of 12 common <i>CFTR</i> gene mutations showing a compound heterozygote for F508del/IVS8-5T. The fluorescence intensity is represented on the Y axis of the electrophoreogram and the fragments’ size on the X axis. N = normal allele (wild type) M = mutant allele; b-d) Electrophoreograms of samples with different IVS8polyT genotypes: 5T/7T (b), 5T/9T (c) and 7T/9T (d).</p

Strategy for detection of IVS8polyT alleles with single base extension aproach.

<p>a) ‘5T/7T/9T extension primer’ in the presence of 5T allele is extended with dideoxyadenine while in the presence of 7T/9T alleles is extended with dideoxythymidine; b) ‘7T/9T extension primer’ in the presence of 7T allele is extended with dideoxyadenine while in the presence of 9T allele is extended with dideoxythymidine. Results of the two primers extension reactions give the final genotype. Extension primer sequences are given in 5′->3′ orientation, while the alleles represent the complementary (minus) strand.</p
