Description

Thermo Scientific™ Prestained Protein Molecular Weight Marker is a mixture of six blue-stained natural proteins (20 to 120kDa) for use as size standards in protein electrophoresis (SDS-PAGE).

This 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.

Highlights:

• Size range – six proteins spanning 20 to 120kDa

• Ready-to-use – supplied in a loading buffer for direct loading on gels

• Prestained – for direct viewing during electrophoresis

• Quality tested – each lot evaluated by SDS-PAGE and Western blotting

Includes:

Dye-stained proteins in 62.5mM Tris-HCl (pH 7.5 at 25°C), 1mM EDTA, 2% SDS, 10mM DTT, 1.5mM NaN₃ and 33% glycerol; Component proteins: beta-galactosidase (120kDa), bovine serum albumin (85kDa), ovalbumin (50kDa), cardonic anhydrase (35kDa), beta-lactoglobulin (25kDa), lysozyme (20kDa)

Recommended for:

Monitoring protein migration during SDS-polyacrylamide gel electrophoresis; Monitoring protein transfer onto membranes after Western blotting; Sizing of proteins on SDS-polyacrylamide gels and Western blots
