Electrophoresis > Ladders and Markers Products & Reviews

Thermo Scientific has a comprehensive range of DNA molecular weight markers which can be sub-divided into three groups: 1. Superladders derived from cloned and purified DNA fragment repeats, for quantitation and accurate sizing 2. High molecular weight markers from lambda DNA restriction digests 3. Lower molecular weight markers from plasmid and ØX174 restriction digests Most of these markers are now also available in a conven…

Perform high sensitivity protein electrophoresis with the 2100 Bioanalyzer System. The High Sensitivity Protein 250 assay provides a broad dynamic range with sensitivity down to Silver Stain comparable levels. Efficiency is enhanced by eliminating handling of SDS-PAGE slab gels, staining or, imaging steps.

The Supercoiled DNA Ladder contains fragments from 2 kb to 10 kb at 1-kb increments and an additional band at 12 kb. Each supercoiled band is at a known concentration, with the 7-kb band at a higher concentration than the others. The resulting brighter band in the middle of the ladder acts as a useful reference point.  Accurate size determination facilitated by evenly spaced bands  Fragments are exact multiples of 1000 bp…

Odyssey One-Color Protein Molecular Weight Markers fluoresce in the 700nm channel of any of the Odyssey Imaging Systems and contain ten protein bands of 10, 15, 20, 25, 37, 50, 75, 100, 150, and 250 kDa, with molecular weight shifts of 5% and minimal band broadening.

Chameleon®  Pre-Stained Protein Ladders offer easy visualization of gel migration and protein size, and can be used to orient your gel or membrane quickly. These versatile protein markers offer multi-colored, pre-stained proteins for both visual inspection and two-color near-infrared detection. Choose from either single-channel or two-channel detection.

Chameleon Vue Pre-stained Protein Ladder offers multi-colored, pre-stained proteins for molecular weight estimation

Chameleon Duo Pre-stained Protein Ladder provides multi-colored, pre-stained bands for visual inspection and two-color near-infrared detection. It includes 11 protein bands from 8 to 260 kDa.

The BenchTop DNA Markers, supplied in a stabilizing solution of 1X Blue/Orange Loading Dye, come in a variety of different sizes to meet your DNA electrophoresis needs.

OxyBlot™ Protein Standard is composed of five proteins (phosphorylase B, BSA, ovalbumin, carbonic anhydrase, trypsin inhibitor) containing 1-3 dinitrophenylhydrazone (DNP) residues per protein. These attached DNP moieties permit the visualization of the proteins by the detection system of the OxyBlot™ Protein Oxidation Detection Kit. OxyBlot™ Protein Standard serves as an internal control for the electrophoresis, western trans…

CpGenome™ Universal Methylated DNA is enzymatically methylated human male genomic DNA. This product is intended for use with the CpGenome™ DNA Modification Kit (S7820) or with amplification primers. It can be used as a methylation-positive control for gene methylation studies.
