What is a Protein Marker or Protein Ladder?

A protein marker (also called a protein molecular weight marker, a protein MW marker, or a protein ladder) is used to estimate the size of proteins resolved by gel electrophoresis.

  • All markers are optimized for use with LI-COR imaging systems but can be used with other imagers.
  • LI-COR protein ladders and markers are visible on the gel during the run, so you can monitor protein migration.
  • Markers are used to monitor transfer efficiency from gel to blotting membrane.
