BlueAQUA Prestained Protein Ladder

Size: 500 μl



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

The BlueAQUA Prestained Protein Ladder is a blue protein standard with 11 pre-stained proteins covering a wide range molecular weights from 10 to180 kDa. Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 72 kDa respectively) are enhanced in intensity when separated on SDS-PAGE (Tris-glycine buffer).

The BlueAQUA Prestained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute, add reducing agent before loading.

 

Guide for Molecular Weight Estimation (kDa)

Migration patterns of BlueAQUA 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.
• 1.5~2.5 μl per well for general Western transferring.
• Apply more for thicker (> 1.5 mm) or larger gel.

Contents : 
Approximately 0.1~0.5 mg/ml of each protein in the buffer (20 mM Tris-phosphate, pH 7.5 at 25°C), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol).

Quality Control : 
Under suggested conditions, BlueAQUA Prestained Protein Ladder resolves 11 major bands in 15% SDS-PAGE (Tris-glycine buffer) and after Western blotting to a 
nitrocellulose membrane.

Storage : 
Stable for up to 3 months at 4°C
Stable for up to 2 weeks at 25°C
For 
long-term storage, store at -20°C
