Protein Markers

abm provides a range of protein markers or ladders in multiple size ranges to aid with simplified estimation of protein sizes during Western Blotting. All the bands are clearly distinct using standard Western Blotting protocols and evenly distributed throughout the ranges providing a reliable tool for protein research.


Our Protein Ladders have a number of desirable properties including:

  • visually distinct and sharp reference bands
  • different colored bands for easy identification
  • four unqiue marker ranges and patterns
  • ready to use and directly load onto an SDS-PAGE gel, no boiling or chemical treatment required
