PageRuler™ Plus pre-stained protein ladders are a mixture of nine blue-, orange- and green-stained proteins (10 to 250 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.
Supplied in a loading buffer for direct loading on gels, no need to boil
Colour-coded bands of similar intensity for easy visualisation
Evaluated by SDS-PAGE and Western blotting
Bright reference bands with orange at 70 kDa and 25 kDa and green at 10 kDa
This pre-stained 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.
A blue chromophore is bound to all proteins, except proteins of two reference bands of 70 kDa and 25 kDa that are colored with an orange dye and one green reference band of 10 kDa.
Packaging: Kit includes dye-stained proteins in 62.5 mM Tris-H₃PO₄ (pH 7.5 at 25 °C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN₃ and 33% glycerol.
Molecular Weight: 250, 130, 100, 70, 55, 35, 25, 15, 10 kDa
Quantity: 2 x 250 μL
Contents: two vials of 250 µL each
