The TrackIt™ 1 Kb Plus DNA Ladder is suitable for sizing linear double-stranded DNA fragments from 100 bp–12 kb. The ladder is prepared from a plasmid containing repeats of a 1,000 bp DNA fragment. The 1,650 bp band is generated from pUC and all bands <1,000 bp are from lambda DNA. The TrackIt™ 1 Kb Plus DNA Ladder is formulated with two unique tracking dyes, Xylene Cyanol FF (XCFF) and tartrazine, that allow you to visually track DNA migration during electrophoresis and also indicate when maximum resolution is achieved. The tracking dyes do not obscure the visualization of DNA bands in the ladder as the dyes run outside the limits of most DNA bands in the ladder. Important features of this ladder:

• Consists of 12 bands in 1,000 bp increments ranging in size from 1–12 kb, a 1,650 bp fragment, and vector DNA fragments from 100–850 bp
• Orientation doublet at 1,650 bp and 2,000 bp for easy reference
• Formulated with unique tracking dyes, XCFF and tartrazine
• Designed for use with E-Gel® agarose gels and TBE/TAE agarose gels
• Supplied in a ready-to-load format, stable at room temperature
• Visualized with ethidium bromide or SYBR® Green staining
For Research Use Only. Not for use in diagnostic procedures.
