BlueStar Prestained Protein Marker

The BlueStar Prestained Protein Ladder is a three color protein standard with 10 prestained proteins covering a wide range molecular weights from 10 to 180 kDa. The BlueStar Prestained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon or nitrocellulose) and for approximating the size of proteins.

Storage Buffer

20 mM Disodium hydrogen phosphate pH 8.0 (at 25°C ), 2 % SDS, 0.2% Triton X-100,10 mM 2-Mercaptoethanol, 6 M Urea and 27% (v/v) Glycerol.


Stable at -20°C for 12 months.
Stable at +4°C for 3 months.

Recommendations for Loading

1. Thaw the ladder either at room temperature or at 37-40°C for a few minutes to dissolve precipitated solids. Do not boil.
2. Mix thoroughly, to ensure that the solution is homogeneous.
3. Load the following volumes of the ladder on SDS-polyacrylamide gel:

  • 5 μl per well for mini-gels, 3 μl per well for blots
  • 10 μl per well for large gels, 6 μl per well for blots



• Monitoring of protein migration during SDS-polyacrylamide gel electrophoresis

• Monitoring of protein transfer onto membranes during Western blotting

• Sizing of proteins on SDS-polyacrylamide gels and Western blots
