The Quick-Load 1 kb Extend DNA ladder is a pre-mixed, ready-to-load molecular weight DNA marker containing bromophenol blue dye as a tracking dye

The DNA Ladder consists of proprietary plasmids and DNA molecules which are digested to completion with appropriate restriction enzymes to yield 13 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 0.5 to 48.5 kilobases. The 3 kb fragment has increased intensity to serve as reference band.
