Description

Thermo Scientific Prestained Protein Molecular Weight Marker is a mixture of six (6) blue-stained natural proteins (20 to 120kDa) for use as size standards in protein electrophoresis (SDS-PAGE).

Features of Prestained Protein Molecular Weight Marker:

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

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.

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

Applications:
• 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
For Research Use Only. Not for use in diagnostic procedures.
