BlueStar Prestained Protein Marker
The BlueStar Prestained Protein Ladder is a three color protein standard with 10 prestained proteins covering a wide range molecular weights from 10 to 180 kDa. The BlueStar 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.
- Broad range: 10 – 180 kDa
- High performance: 10 bands with 3 colours (blue, orange and green)
- Reference bands: 28 kDa (green) and 75 kDa (orange)
- Sharp bands
- Ready to use: Supplied in a loading buffer for direct loading
Storage Buffer
20 mM Disodium hydrogen phosphate pH 8.0 (at 25°C ), 2 % SDS, 0.2% Triton X-100,10 mM 2-Mercaptoethanol, 6 M Urea and 27% (v/v) Glycerol.
Storage
Stable 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

Very good product. The range of the protein ladder is for our purposes perfect.
Nicely visible protein ladder.
We use it as our standard protein ladder for gel electrophoresis.

We have been using Nippon Genetics protein markers in our laboratory for the past 7 years. They are easy to use and exceptionally cost-efficient. The range of the molecular weights is very broad so we can use them for all of our SDS-polyacrylamide gel applications. The bands are sharp and focused and very easily identifiable by the reference colors. Overall, we are extremely satisfied with the quality of these markers.

Wir benutzen die Protein Marker von Nippon Genetics seit 7 Jahren in unserem Labor. Sie sind leicht anzuwenden und besonders preisgünstig. Der Molekulargrößenbereich ist sehr umfassend, so dass wir die Marker für alle unsere SDS-Polyacrylamidgelapplikationen benutzen können. Die Banden sind scharf, klar und durch die Referenzfarbbanden sehr einfach identifizierbar. Insgesamt sind wir sehr zufrieden mit der Qualität dieser Marker.
