ProteoLadder 125 (14.7 kDa - 125 kDa)

(Cat# 12510)

For precise sizing of proteins using SDS-PAGE

  • Ready-to-use and highly stable
  • Recombinant proteins of known amino acid sequence and mass
  • 8 discrete protein bands from 14.7 kDa to 125 kDa
  • Sufficient amount to load 100 gel lanes

The ProteoLadder 125 Ladder is ideal for the accurate molecular weight sizing of proteins by SDS-PAGE. The proteins separate into concise bands from 14.7 kDa to 125 kDa when analyzed by SDS-PAGE and stained with Coomassie Blue.

0.5 mL of ready-to-use mix comprised of 8 purified recombinant proteins in loading buffer (50mM Tris HCl, pH 7.5, 100mM DTT, 0.01% Bromophenol Blue, 1mM EDTA, 1mM Sodium Azide, 2% SDS and 20% Glycerol).


  • Ready-to-use
  • Highly stable
  • 8 discrete protein bands from 14.7 kDa to 125 kDa
  • Precise
