NeoPRO 10 Prestained Protein Ladder


  • The NeoPRO 10 Prestained Protein Ladder (NB-59-0002) is a combination of 10 pre-stained proteins with molecular weights ranging from 6.5 to 270 kDa.
  • The 10 recombinant proteins in the ladder are covalently coupled with a blue chromophore.
  • The ladder includes 2 orange bands at 30 kDa and 270 kDa, as well as a green band at 52 kDa, which function as reference bands.
  • It is designed to monitor the size and separation of proteins during SDS-polyacrylamide gel electrophoresis.
  • The NeoPRO 10 Prestained Protein Ladder helps estimate protein size and validate the efficiency of Western transfer on PVDF, nylon, or nitrocellulose membranes.


Guide for Molecular Weignt Estimation ( KDa)




• One-Vial-Fits-All: New broad-range protein ladder from 6.5kDa to 270kDa.

• Higher Added Value: Tri-colors and 10 bands with premium quality.

• Better performance for higher molecular weight proteins.

• Clear separation map from 6.5 kDa to 270 kDa in the Tris-Glycine system.

• Enhanced transfer, wash, and stripping durabilities.


Important notes

The molecular weight of each protein (kDa) was measured against an unstained protein ladder in every electrophoresis condition. Additional data should be considered for a more accurate adjustment.
