Thermo Scientific™ Spectra™ Multicolor Low Range Protein Ladder
A mixture of six proteins and synthetic peptides (1.7 to 40kDa) for use as size standards for peptides and small proteins in gel electrophoresis and Western blotting.
Brand: Thermo Scientific™ 26628

DescriptionThis prestained protein MW marker is designed for monitoring the progress of SDS-polyacrylamide gel electrophoresis, for assessing transfer efficiency onto PVDF, nylon and nitrocellulose membranes, and for estimating the approximate size of separated proteins that have been made visible with gel stains or Western blot detection reagents. Three different chromophores (blue, orange, green) are bound to the different component proteins, producing a brightly colored ladder with an easy-to-remember pattern. The Spectra Multicolor High Range Protein Ladder is ready to use: no heating, further dilution or addition of a reducing agent is required.
Size range – six proteins and peptides spanning 1.7 to 40kDa
Multicolor – three different colors for unambiguous band-size assignment
Ready-to-use – supplied in a loading buffer for direct loading on gels; no need to boil
Sharp bands – color-coded bands of similar intensity for easy visualization
Quality tested – each lot evaluated by SDS-PAGE and Western blotting
Membrane-compatible – colored bands transfer to membranes for Western blotting
Dye-stained proteins in 62.5mM Tris-H3PO4 (pH 7.5 at 25°C), 1mM EDTA, 2% SDS, 10mM DTT, 1mM NaN3 and 33% glycerol.
Monitoring of protein migration during SDS-PAGE; Verifying Western transfer efficiency; Approximate sizing of proteins on SDS-polyacrylamide gels and Western blots; Locating a protein of interest for excision from an unstained preparative gel
