AMPIGENE® DNA ladder contains DNA fragments ranging from 50 bp to 1500 bp that can be used as molecular weight standards for agarose gel electrophoresis. The bands are evenly spaced and are intensified at 200 bp, 500 bp and 1500 bpto serve as easily identifiable reference bands. The approximate mass of DNA in each of the bands is provided, assuming 5 µl load, for determining the approximate mass of DNA in samples with comparable intensity and sizes.

Lambda phage consists of a virus particle including a head (also known as a capsid), a tail and tail fibres. The head contains the phage's double-stranded circular DNA genome. The phage particle recognises and binds to its host E.coli causing DNA in the head of the phage to be ejected through the tail into the cytoplasm of the bacterial cell. Lambda phage DNA is commonly used as a DNA molecular weight marker. Digestion of the lambda phage genome with HindIII produces a set of 8 fragments consisting of 125, 560, 2000, 2300, 4300, 9400, and 23000 base pairs.

FastRuler ultra low range DNA ladder is specifically designed for fast sizing and approximate quantification of double-stranded DNA in 48 well (or 96-well) high throughput gels, as well as in conventional agarose gels. The ladder is a mixture of five blunt-ended chromatography-purified individual DNA fragments that are easily resolved in a short separation distance (10 to 20 mm) after an 8 to 14 minutes run on the appropriate agarose gel.

Supplier: Thermo Fisher Scientific

Thermo Scientific™ GeneRuler™ and O'GeneRuler™ DNA ladders are mixtures of chromatography-purified individual DNA fragments. The GeneRuler™ line includes the most popular ladders, such as the 100 bp and 1 kb DNA Ladder. GeneRuler™ DNA ladders are available in two formats: Conventional (provided in TE buffer) and a ready-to-use format (premixed with 6X DNA Loading Dye which contains bromophenol blue and xylene cyanol FF). O'GeneRuler™ DNA ladders are another ready-to-use version of GeneRuler™ DNA ladders that are premixed with 6X Orange DNA Loading Dye.
