TrackIt™ DNA Ladders
 | TrackIt™ DNA Ladders are supplied premixed in loading buffer containing tracking dyes that run behind and ahead of the sample, ensuring the DNA bands will not be obscured by the dyes. TrackIt™ DNA Ladders are stable at room temperature and can be stored on your benchtop. There is no need to heat, mix, or dilute these ladders prior to loading them on your gel. |
