From: Performance of cellulose-based card for direct genetic testing of spinal muscular atrophy
PCR-RFLP results from the dried blood spots on the cellulose-based card (DBSc), FTA card (DBSf) and gDNA. A Electropherogram of SMN exon 7 digestion showing SMN1 exon 7 fragment (187 bp) and SMN2 exon 7 fragment (163 bp). B Electropherogram of SMN exon 8 digestion showing SMN1 exon 8 fragment (189 bp) and SMN2 exon 8 fragments (123 bp and 66 bp). M = DNA ladder with indicated fragment size. Lanes 1, 3 and 5 were from SMA patients. Lanes 2, 4, and 6 were from healthy proband. BP = blank paper
