1. Gently mix the Unstained Protein Ladder, Broad Range (NEB #P7703 ) by gently vortexing or pipetting up and down several times.
2. Incubate at 95°C-100ºC for 5 minutes.
3. Centrifuge quickly.
4. Aliquot in to single use aliquots and store at -20C.

What is marker in SDS-PAGE?

Protein molecular weight markers, sometimes referred to as protein standards or protein ladders, are used to estimate the molecular weight of proteins of interest and to monitor the progress of electrophoretic separation or transfer in Western blotting.
