PCR-RFLP of SMN exon 7 results of DBSc over storage period. A Pre-digestion PCR product of SMN exon 7 (187 bp). B Post-digestion PCR products showing SMN1 exon 7 fragment (187 bp) and SMN2 exon 7 fragment (163 bp). M = DNA ladder. Lane 1 = DBSc stored for 1 day, Lane 2 = DBSc stored for 1 week, Lane 3 = DBSc stored for 2 weeks, Lane 4 = DBSc stored for 3 weeks, Lane 5 = DBSc stored for 4 weeks, Lane 6 = DBSc stored for 2 months, Lane 7 = DBSc stored for 3 months, Lane 8 = control blank paper, Lane 9 = gDNA
