Purpose and Application

  • Low molecular weight protein marker (about 1,000~29,000 Da) for SDS-PAGE


  • sharp and clear band
  • Wide molecular weight range 1,000Da ~ 29,000Da
  • Store for one year and refrigerate for six months.


Tips for Low Molecular Weight Protein Electrophoresis

Electrophoresis of proteins and polypeptides with a molecular weight of around 20,000 Da or less is difficult to separate in the usual SDS-PAGE (Laemmli method), so the electrophoresis is carried out with tris-tricin buffer (AE-1415 EzRunT).

Gels and electrophoresis buffers are used exclusively for low molecular weight protein separation. The minimum time for the migration is about 65 minutes, and the migration is completed faster than before.

Low molecular weight proteins and polypeptides can spread if it is not fixed immediately after migration or not stained for a short period of time. CBB staining with AE-1340 EzStain AQua can be stained and destained for a short time using the microwave oven method.
