In all DNA-electrophopresis methods the DNA run negatively charged to the anode!
There are 3 different main DNA-electrophoresis methods:
Native samples run in native gels: d(ouble) s(dranded)-DNA electrophorese
ds: Easy method, 1 fragment = 1 band, but no exact molecular weights
(because of the double-stranded conformation polymorphisme)
Denaturated samples run in denaturated gels: s(ingle)-s(tranded) denatured electrophoresis
ss: Difficult method, 1 fragment = 2 bands (PCR-anomaly), but exact molecular weights
(method used in all sequencers)
Denaturated samples run in native gels: s(ingle)-s(tranded) conformation polymorphisme electrophoresis
sscp: No molecular weights but sequence-related run (= mutation-detection)
