The Blu10 Prestained Protein Ladder is a combination of 10 pre-stained proteins with molecular weights from 11 to 180 kDa. The 10 recombinant proteins are covalently coupled with blue chromophore, while 1 green band at 25 kDa and a red band at 75 kDa, serve as reference bands. The Blu10 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.
Molecular Weight Estimation (kDa)
Migration patterns of Blu10 Prestained Protein Ladder in different electrophoresis conditions are listed below :
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.
Storage Buffer
Approximately 0.2~0.4 mg/ml of each protein in buffer (20 mM Trisphosphate pH 7.5 at 25°C), 2% SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15% (v/v) Glycerol.
Storage
- Stable for up to 2 weeks at 25°C.
- Stable for up to 3 months at 4°C.
- Stable for up to 24 months at -20°C.
