You Searched For: Molecular Weight Markers

Molecular-weight size markers are a set of standards used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. The molecular weight markers offered are ideal for verification of PCR products, for size analysis of digested DNA, and easy band identification of a number of different fragments. Certain models are available pre-mixed with loading dye.

DNA ladder 50 to 1500 bp, AMPIGENE®

Catalog Number: (ENZOENZGEN1020100)
Supplier: ENZO LIFE SCIENCES
Description: 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.

DNA ladder, O'RangeRuler™

Supplier: Thermo Fisher Scientific
Description: O'RangeRuler™ DNA ladders are step ladders that consist of basic unit repeats of 10, 15, 20, 50, 100, 200, or 500 bp. The ladders have a higher density of bands at a specific DNA size range and are therefore suitable for more accurate sizing of DNA in agarose or non denaturing polyacrylamide gels.

Product Image-SM0101

Lambda DNA/HindIII Marker

Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Lambda DNA/HindIII Marker is recommended for sizing of linear double-stranded large DNA fragments in agarose gels. Lambda DNA is digested to completion with the appropriate restriction enzyme(s) and purified and dissolved in storage buffer. DNA fragments contain various sticky ends depending on the restriction enzyme used for preparation of the marker.

DNA ladders, ultra low range, FastRuler

Catalog Number: (SM1103)
Supplier: Thermo Fisher Scientific
Description: 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.

Lambda DNA phage, E. coli W8850

Catalog Number: (ROCKMB-104-0500)
Supplier: Rockland Immunochemicals
Description: 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 <i>E.coli</i> 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.
