Invitrogen Ultra Low Range DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA in the range of 10 bp to 300 bp. Ultra Low Range DNA Ladder consists of nine individual chromatography-purified DNA fragments with a reference band at 100 bp for easy orientation.

Ultra Low Range DNA Ladder is ideal for separation on 4–5% agarose gels.

Highlights of Ultra Low Range DNA Ladder:
• Sharp, clear bands—chromatography-purified fragments for consistent and reliable results
• Convenient—provided with 6X TrackIt Cyan/Yellow Loading Buffer for tracking of DNA migration
• Precise—an exact amount of DNA in each band

Product use
The double-stranded DNA ladder can be visualized on 4–5% agarose gels after ethidium bromide or SYBR Safe staining. The ladder is designed with a uniform intensity of DNA bands for a clear view of each band. An exact amount of DNA in each band allows approximate quantification of DNA samples.

This ladder can be radiolabeled with T4 polynucleotide kinase or T4 DNA polymerase.
