Reconstitute each vial with 100 uL of deionized water. Vortex for a few seconds to ensure the material is completely dissolved. After reconstitution, immediately aliquot and store the unused portion below –20 °C. Repeated freezing and thawing of reconstituted SigmaMarkers is not recommended.

Application
SigmaMarker has been used as a protein marker in sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE).
SigmaMarkers are designed for use with Laemmli SDS-PAGE, the PhastSystem (Pharmacia) and Schagger and von Jagow SDS-PAGE (Tricine). SigmaMarkers cover the range of molecular weights common to most proteins or their subunits. The wide, high and low range markers are lyophilized with sample buffer so that they are ready-to-use after reconstitution with deionized water. The markers are formulated to yield a distribution of well-defined bands of approximately equal intensity after electrophoresis and Coomassie blue staining.
Preparation Note
Reconstitution with 100 μl of deionized water results in a solution containing 2-3.5 mg of protein per ml of 62 mM Tris-HCl, pH 6.8, 1 mM EDTA, 4% sucrose, 10 mM TCEP, 2% SDS, and 0.01% bromophenol blue.
