Protein ladder PS11 contains 11 proteins that resolve into sharp, tight bands in the range of 10-175 kDa. The Protein Ladder allows to monitor molecular weight separation during electrophoresis, estimate molecular weights The marker is ready-to-use. There is no need to boil. Easy to identify: includes the ~10, ~40 and ~90 kDa reference bands coupled with an blue dye
• 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.
Mini gel application: 5 μl/well; 2.5 µl per well blots
Standard gel application: 10 μl/well; 5 µl per well for blots
Number of bands: 11 10.5, 14, 22, 29, 42, 51, 62, 70, 95, 130, 175 kDa
Loading Denaturing Polyacrylamide gels (SDS-PAGE):
- Thaw marker at room temperature or heat at 37 – 40 °C for a few minutes. Do not boil!
- Vortex gently to ensure the solution is
homogeneous and load the ladder on SDS-
- 5 μl per well for mini-gels, 2.5 μl per well for blots
- 10 μl per well for large gels, 5 μl per well for blots
1 ml marker is sufficient for 200 mini gels or 100 standard gels.
It is recommended to divide the marker into aliquots to avoid contamination of the stock solution.
Protein Marker PS11 is optimized for runs on 15 % SDS polyacrylamide gels. 4 to 12 % gels may cause
proteins with low molecular weights to migrate with the dye front. On 12 to 15 % and gradient gels all bands are visible.
Tested in SDS-polyacrylamide gel electrophoresis and Western blotting.
Storage: at -20°C
Shipment: on blue ice
Protein Molecular Weight Marker PS11 (prestained) is ideal for precise sizing of proteins by SDS-PAGE and for Western blotting.
