DNA molecular weight ladders stained with SYBR® Green I Nucleic Acid Gel Stain.
DNA molecular weight ladders that were electrophoresed on a 1% agarose gel were stained for 30 min with a 1:10,000 dilution of SYBR® Green I Nucleic Acid Gel Stain (Cat. No. S7563, S7567, S7585). Lanes 1 and 8 contain HindIII–cut DNA; lanes 2 and 7, HaeII–cut fX174 RF DNA; lanes 3 and 6, 1 kilobase pair DNA ladder (Life Technologies); lane 4, 100 Base Pair DNA Ladder (Life Technologies); lane 5, EcoRI–cut pUC19 DNA mixed with PstI–cut fX174 RF DNA. Gel staining was visualized using 254 nm epi-illumination.
