DynaMarker® Protein MultiColor Stable, Low Range is a pre-stained protein molecular weight marker. The marker is supplied in gel loading buffer for direct loading onto SDS-PAGE without heating or adding reducing agents. It is easy to start electrophoresis since the marker can be stored and stable at 4 °C in a liquid state. The marker consists of seven prestained protein standards, Blue, Red, Green and Purple, ranging in appropriate molecular weight from 2 kDa to 46 kDa. The marker is suitable for monitoring gel electrophoresis and electrophoretic transfer onto membranes. The protein concentrations are optimized to give uniform band intensitieseHigh Quality Prestained Protein Markers - Low M.W. Rang




DynaMarker® Protein MultiColor Stable, Low Range

16% (C3%) Polyacrylamide gel
Running buffer: Tris-Tricine-SDS


DynaMarker® Protein MultiColor Stable, Low Range is suitable for low molecular protein analysis. This marker is stable at 4°C for as long as one year. 

  • Stable at 4°C for as long as 1 year. The high stability keeps the sharpness of bands. 
  • Suitable for monitoring gel electrophoresis and transferring onto membrane.
  • Stable to wash buffers (TBST or PBST) and stripping buffers containing 0.1% Tween-20 for western blotting. 
  • only for use with Tris-Tricine-SDS electrophoresis buffer.


Fig1. Detection of β-Amyloid
β-Amyloid (1-42) and this marker were transferred onto nitrocellulose membrane, and detected with anti-β-Amyloid antibody and DAB stain.
These colored bands of this marker remained on the membrane through the western blotting.
In addition, the apparent molecular weights of colored bands were accurate.



Fig2. Stability of colored bands on PVDF membrane against harsh stripping buffer
This marker was transferred onto PVDF membrane, and then PVDF membrane was incubated in harsh stripping buffer (containing 2% SDS and 0.1 M 2-mercaptoethanol) at 50°C for 45 minutes.
These colored bands kept visible clearly, even after the stripping buffer treatment.
*Depending on the membrane type or stripping buffer composition, these color bands may become pale..


1. Take the marker out of refrigerator.
2. Load 5 μl for mini-gels or more for large size gels.
3. Load your samples.
4. Start electrophoresis.

Note: There is no need to heat or add reducing agents.

As covalently bound dye affects protein mobility, each batch of our prestained protein marker is calibrated against unstained standards. A prestained protein marker should be used for approximate molecular weight determination. For precise molecular weight determination, you should use an unstained molecular weight marker. * : The apparent molecular weight values are lot specific.

Recommended usage
DynaMarker® Protein MultiColor Stable, Low Range is suitable for monitoring low molecular weight protein on polyacrylamide gel electrophoresis using Tris-Tricine-SDS as running buffer (1), and for monitoring electrophoretic transfer.

Heat at 95°C for 5 min, and then put the tube on ice.

1-4) Electrophoresis of the protein samples and DynaMarker® Protein MultiColor Stable, Low Range.
Set the Polymerized acrylamide gel in the electrophoresis apparatus, then pour the 1× Anode buffer and
1× Cathode buffer. Load the protein sample and 5 μl of DynaMarker® MultiColor Stable, Low Range into a
well and run the gel at 100−200 V.
2) Transfer onto membrane
2-1) Preparation of reagents
  • Transfer buffer (Towbin buffer) 25 mM Tris, 192 mM Glycine, 20 % MeOH
  • Nitrocellulose membrane (0.2 μm pore size).
Note: Transfer efficiency differs depending on the type of membranes and buffers, because the physical properties of small molecule proteins greatly vary depending on kinds of proteins.

2-2) Semi-dry transfer
2-2-1) Prepare six sheets of blotting paper and a sheet of nitrocellulose membrane.
2-2-2) Soak the blotting paper and nitrocellulose membrane with transfer buffer for 10 min.
