BlueRAY Prestained Protein Ladder 10 to 180 kilodalton (kDa).

Short Description

Cat No: RB006-600

The BlueRAY Prestained Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range molecular weights for 10 to 180 kilodalton (kDa). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-polyacrylamide gel electrophoresis (SDS-PAGE) with Tris-glycine-SDS running buffer. The BlueRAY Prestained Protein Ladder is designed for monitoring protein separated during SDS-PAGE, verification of Western transfer efficiency on membranes (PVDF, nylon or nitrocellulose), and for approximate sizing of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heats, dilute, and add reducing agent before loading.

Applications
• Monitoring of protein migration during SDS-PAGE.
• Monitoring of protein transfer onto membranes during Western blots.
• Sizing of proteins on SDS-PAGE gels and Western blots.

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
The quality of the BlueRAY Prestained Protein Ladder is tested on a lot-to-lot basis to ensure consistent product quality.

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

BlueRay Prestained Protein Ladder Protocol
1. Thaw the ladder either at room temperature or at 37-40°C for a few minutes to dissolve precipitated solids. Do not boil.
2. Mix thoroughly to ensure the solution is homogeneous.
3. Load the following volumes of the ladder on SDS-PAGE gel:
• 5 μl per well for mini-gels, 2.5 μl per well for blots
• 10 μl per well for large gels, 5 μl per well for blots
• Apply more for thicker (> 1.5 mm) or larger gel
