Description
The BlueRAY Prestained Protein Ladder is a three-color protein standard with 10 prestained 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.

Features

• Broad range: 10-180 kDa (Tris-glycine-SDS running buffer)
• Ready-to-use: supplied in a loading buffer for direct loading on gels
• Easy to identify: includes the ~25, ~75 kDa reference bands coupled with a green and a red dye
• Sharp bands

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.
