Marcador de proteínas BlueStar Plus para electroforesis, 1 tubo con 500µl

BlueStar PLUS Prestained Protein Marker

The BlueStar PLUS Prestained Protein Marker is a three color protein standard with 12 prestained proteins covering a wide range molecular weights from 10 – 240
kDa. The 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 approximate sizing of proteins.

• Broad range: 10 – 240 kDa
• High performance: 12 bands with 3 colours (blue, red and green)
• Ready to use: Supplied in a loading buffer for direct loading on gels
• Easy to identify: The 25 (green) and 75 kDa (red) are reference bands
• Sharp bands 

Contents

Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate, 2 % SDS, 10 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol).

Storage

Store at -20°C for 12 months.
Stable at +4°C for 3 months.

Recommendations for Loading

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 that the solution is homogeneous.
3. Load the following volumes of the ladder on SDS-polyacrylamide gel:
   – 5 μl per well for mini-gels, 3 μl per well for blots;
   – 10 μl per well for large gels, 6 μl per well for blots
