Single-strand conformation polymorphism of hyper-variable regions HV1 and HV2 of human mitochondrial DNA: detection by silver staining.

Human mitochondrial DNA from 50 trios consisting of mother (M), child (C) and father (F) was PCR amplified with primers flanking the hyper-variable regions, HVR1 and HVR2. The amplified products were then fractionated under non-denaturing conditions, silver-stained and compared by single-stranded conformational polymorphism (SSCP). In all but one case, mother and child displayed identical patterns, which could be promptly distinguished from that of the father.
