Thermo Scientific™ Invitrogen™ TrackIt™ 100 bp DNA Ladder, 50 µg

The Invitrogen™ TrackIt™ 100 bp DNA Ladder is a ready-to-use molecular weight marker designed for the accurate sizing and approximate quantification of double-stranded DNA fragments ranging from 100 to 2,000 base pairs. This ladder consists of 13 chromatography-purified DNA fragments, with reference bands at 2,000 bp, 1,500 bp, and 600 bp to facilitate easy identification and orientation during electrophoresis.

Each band contains a defined amount of DNA, enabling both visual sizing and approximate quantification when run alongside experimental samples. The ladder is pre-mixed with 6X TrackIt™ Cyan/Orange Loading Buffer, providing enhanced visibility and tracking during agarose gel electrophoresis.
