DNA Ladders

Life Technologies supplies a wide range of DNA ladders and markers for accurate size and mass estimation (quantitation) of DNA fragments. DNA ladders and markers are available for sizing double-stranded, single-stranded, or supercoiled DNA.

A variety of these DNA ladders and markers are also available in the ready-to-load TrackIt™ format. There is no need to heat, mix, or dilute these markers prior to loading them on your gel. TrackIt™ markers contain two tracking dyes that indicate when maximum resolution of the DNA fragments has been achieved.
