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.

Product Image-69278-3

PCR Molecular Size Marker

Catalog Number: (69278-3)
Supplier: Merck Millipore (Novagen)
Description: PCR Molecular Size Marker contains a mixture of eight defined DNA fragments ranging from 50 to 2000 bp at convenient size intervals for characterising small DNA products. The markers are supplied in gel loading buffer containing two tracking dyes that do not interfere with UV illumination of ethidium bromide-stained bands. A separate vial of 6X Loading Buffer is included. Each vial of markers is sufficient for 50 lanes on TBE or TAE agarose stained with ethidium bromide. The recommended amount for loading (5 µl) produces bands of even intensity that are bright, sharp and easy to photograph.

DNA ladder, 100 bp

Catalog Number: (A5191.0025)
Supplier: PanReac AppliChem
Description: This DNA ladder is ideal for determining the size of double-stranded DNA ranging from 100 to 1,000 base pairs. The ladder consists of ten fragments that range in size from 100 to 1,000 bp in 100 bp increments. The 500 bp fragment is present at increased intensity to allow easy identification. All fragments are blunt-ended.

DNA QuantLadders

Catalog Number: (LONZ50334)
Supplier: LONZA
Description: QuantLadders are prepared from five highly purified DNA fragments that provide visual quantitation of DNA within ±1% accuracy. The DNA QuantLadder provides each DNA fragment in perfect relative mass equivalence at 100 ng, 70 ng, 50 ng, 20 ng and 10 ng. The reverse QuantLadder simply reverses the mass equivalence order of the QuantLadder.

Western blotting markers, Amersham™ ECL™ DualVue™

Catalog Number: (RPN810)
Supplier: Cytiva
Description: Amersham™ ECL™ DualVue™ Western blotting markers perform two key functions. Firstly, the prestained marker proteins confirm protein transfer in addition to clearly defining blot orientation. Secondly, the recombinant tagged proteins are detected on film or by CCD imaging in conjunction with the target protein(s) of interest, enabling highly accurate molecular mass determination of the target protein(s). The tagged markers are detected easily and specifically by means of a specific conjugate that eliminates any cross contamination between target protein(s) and markers.
