BIO-HELIX - PM006-0500

BlueRAY Prestained Protein Ladder(10 to 180 kDa)

Size: 500 μl



Note: Protein Marker / Protein Standard / SDS-PAGE / Western Blot
Categories: Protein Marker/Ladder

The BlueRAY 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 BlueRAY 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.

 

-Guide for Molecular Weight Estimation (kDa)

Migration patterns of BlueRAY 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.

Note: 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 : 
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.

Quality Control : 
5 μl of BlueRAY Prestained Protein Ladder (PM006-0500) resolves 10 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane.

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.
