Ladders and Markers Products & Reviews

Prestained markers are brighter for visual robustness throughout western blotting to accurately estimate MW, monitor electrophoresis and transfer efficiency.

250 µl, pre-stained, Strep-tagged recombinant proteins (10–250 kD), including three pink reference bands (25, 50, 75 kD), 50 applications

The SeeBlue Plus2 Pre-Stained Standard allows you to easily visualize protein molecular weight ranges during electrophoresis and quickly evaluate Western transfer efficiency.

PageRuler Plus Prestained Protein Ladder is a mixture of nine (9) blue-, orange- and green-stained proteins for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.

Heat shock fraction, protease free, fatty acid free, essentially globulin free, pH 7, ≥98%

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…

The Thermo Scientific 1kb DNA Ladder is and easy reference ladder with brighter bands at 1kb and 3kb.

A number of proprietary plasmids are digested to completion with appropriate restriction enzymes to yield 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 0.5-10.0 kilobases (kb). The 3.0 kb fragment has increased intensity to serve as a reference band. The approximate mass of DNA in each of the bands is provided (assuming a 0.5 μg load) f…

The 1 kb DNA Ladder contains 13 discrete DNA fragments ranging in size from 300 bp to 10,000 bp. This marker is ideal for the size determination of digested DNA. Two Ready-to-Use DNA Size Markers for Gel Electrophoresis. The 100 bp Ladder and 1 Kb Ladder represent the two most popular markers used for DNA fragment size determination. These markers are formulated to run accurately and to provide crips band patterns. The two m…
