Note: Protein Marker / Protein Standard / SDS-PAGE / Western Blot / Protein Electrophoresis


The Blu10 Plus (BLUltra) Prestained Protein Ladder is a combination of 10 pre-stained proteins with molecular weights from 6.5 to 270 kDa. The 10 recombinant proteins are covalently coupled with blue chromophore, while 2 orange bands at 30 kDa and 270 kDa and a green band at 52 kDa serve as reference bands. The Blu10 Plus (BLUltra) Prestained Protein Ladder keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating protein size and validating Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes.


  • Appearance: Liquid
  • Color: Dark blue
  • Odor: Odorless
  • pH-value: Not determined

Reaction Setup

3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. 2.5 μl per well for general Western transferring.

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.

Storage Buffer
