1Kb DNA Ladder is a premixed, ready-to-load molecular weight marker containing eight linear double-stranded DNA fragments. The DNA Ladder is suitable for use as molecular weight standards for agarose gel electrophoresis and is not recommended for use in polyacrylamide gel electrophoresis. The DNA Ladder contains 1.0 -10.0 kb DNA fragments. The 4.0 kb band (100 ng/5 μl) has doubled intensity than other bands to serve as reference band.
