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-A5191.0025

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.
UOM: 1 * 0,25 mg

Protein markers for gel electrophoresis

Catalog Number: (A8889.0500)
Supplier: PanReac AppliChem
Description: The main applications for prestained protein markers are the monitoring of protein migration during SDS-PAGE, verification of Western transfer efficiency on membranes, and estimation of protein sizes on SDS-polyacrylamide gels and Western blots.
UOM: 1 * 500 µl
Product Image-LONZ50330

DNA ladder

Supplier: LONZA
Description: Thse DNA ladders provides rapid and easy size determination of the DNA samples. Each band has an ideal 50 % G-C content for precise sizing and sharp resolution. It is free from contaminating plasmid DNA with minimal background.

Product Image-RPN755E

Molecular weight markers, Rainbow™

Supplier: Cytiva
Description: Rainbow™ molecular weight markers enable faster and simpler identification of proteins on SDS polyacrylamide gels. These ready to load markers provide sharper, more intense bands on gels and blots, and have improved band spacing for more accurate molecular weight determination. The bright, distinctive colours of the markers allow easier confirmation of transfer to blotting membranes and orientation.

Product Image-RPN810

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.
