Thermo Scientific™ Invitrogen™ TrackIt™ Ultra Low Range DNA Ladder, 50 µg

The Invitrogen™ TrackIt™ Ultra Low Range DNA Ladder is a ready-to-use molecular weight marker specifically designed for the accurate sizing and quantification of low molecular weight double-stranded DNA fragments ranging from 10 bp to 300 bp. The ladder contains nine individual, chromatography-purified DNA fragments, premixed with TrackIt™ Cyan/Yellow Loading Dye for ease of use and precise tracking.

A distinct 100 bp reference band enables easy gel orientation, making this ladder particularly well-suited for agarose gel electrophoresis at 4–5% concentrations. Whether used in routine analysis or high-resolution fragment sizing, this ladder delivers sharp, consistent, and reproducible band patterns.

Key Features and Benefits

• Low Range Fragment Coverage: Includes 9 distinct DNA fragments ranging from 10 to 300 bp, ideal for short fragment analysis.
• Reference Band at 100 bp: A distinct, higher-intensity band allows rapid gel orientation.
• Chromatography-Purified Fragments: Produces sharp, clean bands with minimal background or smearing.
• Ready-to-Use Format: Premixed with 6X Cyan/Yellow Loading Dye—no additional preparation required.
• Stable at Room Temperature: Store at room temperature or 4 °C for up to 24 months.
• Green Feature: Comes in sustainable packaging.
