Figure 4From: Electrophoresis of proteins and DNA on horizontal sodium dodecyl sulfate polyacrylamide gelsDifferent DNA molecular mass markers, 100 bp ladder (BioLabs, U.S.A.) (lane 1), Marker V (Roche, USA) (lane 2), 50 bp ladder (Amersham, USA) (lane 3), were electrophoretically fractionated on 5% or 10% polyacrylamide gel with or without SDS, until the dye ran off the gel. Gels were stained with ethidium bromide as described in Materials and Methods.Back to article page
