Gel Loading Solution [6X]
Cat No.: DCP-GLS6X
Size: 3 x 1 mL
Sterile; Ultrapure, Filtered 0.1-micron membrane TWICE and 0.04-micron membrane ONCE.
Description:
Gel Loading Solution (6X) is an essential component for DNA and RNA electrophoresis experiments. It facilitates the loading process by increasing the density of the sample and providing visual tracking. Bromophenol blue and xylene cyanol FF serves as a tracking dye and allows visual monitoring of the electrophoresis progress. Glycerol increases the density of the sample and ensures that the DNA/RNA sample sinks to the bottom of the well when loaded. Gel loading solution is used for non-denaturing polyacrylamide electrophoresis.
* Please note that this buffer contains Bromophenol blue and Xylene cyanol FF.
Advantages:
- Sample density: The high glycerol content (60%) increases the density of the sample, ensuring it sinks to the bottom of the well when loaded onto the gel. This prevents sample loss and improves loading accuracy.
- Nucleic acid protection: EDTA acts as a chelating agent, inhibiting metal-dependent nucleases and protecting DNA/RNA from degradation during electrophoresis.
- Visual tracking: The bromophenol blue serves as a tracking dye, allowing researchers to monitor the progress of electrophoresis visually. In a 1% agarose gel, bromophenol blue migrates with DNA fragments of approximately 300-500 base pairs.
Application:
- Sample preparation: It's used to prepare DNA or RNA samples for loading into agarose or polyacrylamide gels. The recommended usage is typically 1 part buffer to 5-9 parts sample, depending on the specific application.
- Density increase: The high glycerol content (50-60%) increases the density of the sample, ensuring it sinks to the bottom of the well when loaded onto the gel. This prevents sample loss and improves loading accuracy.
- Versatility: This buffer is compatible with both agarose and native polyacrylamide gels, making it suitable for various nucleic acid separation experiments.
- Compatibility with downstream applications: It doesn't introduce components that might interfere with subsequent analyses of the separated nucleic acids.
