Thermo Scientific GeneRuler 1 kb DNA Ladder is recommended for sizing and approximate quantification of a double-stranded DNA in the range of 250 bp to 10,000 bp on agarose gels. The DNA ladder consists of 14 DNA fragments and is provided with 6X TriTrack DNA Loading Dye.

Thermo ScientificTM GeneRulerTM 1 kb DNA Ladder is designed for sizing and approximate quantification of wide range double-stranded DNA on agarose gel. The ladder is composed of fourteen chromatography-purified individual DNA fragments (in base pairs): 10000, 8000, 6000, 5000, 4000, 3500, 3000, 2500, 2000, 1500, 1000, 750, 500, 250.

GeneRuler 1 kb Plus DNA Ladder 75 to 20,000 bp is recommended for sizing and approximate quantification of a wide range of double-stranded DNA on agarose gels. The ladder is a mixture of chromatography-purified individual DNA fragments.

GeneRuler 100bp 100 to 1000bpDNA Ladder is recommended for sizing and approximate quantification of a wide range of double-stranded DNA on agarose or polyacrylamide gels. The ladder is a mixture of chromatography-purified individual DNA fragments. GeneRuler 100bp DNA Ladder can be labeled radioactively with T4 Polynucleotide Kinase (seeProtocol).

Thermo Scientific GeneRuler 100 bp DNA Ladder is recommended for sizing and approximate quantification of a double-stranded DNA in the range of 100 bp to 1,000 bp on agarose or polyacrylamide gels. The DNA ladder consists of 10 DNA fragments and is provided with 6X TriTrack DNA Loading Dye.

DNAmark™ 50bp Plus Ladder consists of 13 fragments ranging from 50-1000 base pairs (bp). This molecular weight marker is specially designed for identifying small DNA fragments and allowing for quantitative estimation of the DNA fragments in the gel at the same time.

Thermo Scientific GeneRuler DNA Ladders contain mixtures of individual chromatography-purified DNA fragments, designed to deliver precision and ease-of-use for everyday electrophoresis. Request free sample Selection guide. The chromatography-purified DNA fragments in GeneRuler ladders produce high quality reference bands.

The KPL GeneRuler™ Biotinylated DNA Ladder provides a convenient pre-labeled molecular weight marker ideal for use on Southern blots. The digest contains a mixture of labeled and unlabeled DNA, allowing visualization either through ethidium bromide staining or enzymatic detection as desired. Labeled and unlabeled DNA fragments migrate uniformly.

Thermo ScientificTM GeneRulerTM 1 kb Plus DNA Ladder is designed for sizing and quantification of DNA fragments in agarose gels. The ladder is composed of fifteen chromatography-purified individual DNA fragments (in base pairs): 20000, 10000, 7000, 5000, 4000, 3000, 2000, 1500, 1000, 700, 500, 400, 300, 200, 75.
