Electrophoresis Buffers

Electrophoresis Buffers

Making large quantities of buffers necessary for DNA gel electrophoresis and SDS-PAGE is one of the more tedious laboratory responsibilities. Stellar Scientific offers easy-to-use, pre-measured packets of the most common electrophoresis buffers to simplify and accelerate your research, ensuring your lab maintains peak productivity without the hassle of manual mixing.

Why Choose Stellar Scientific Electrophoresis Buffers?

QuickSilver™ Convenience

Our QuickSilver™ line features pre-measured buffer pouches that eliminate the need for weighing out raw chemicals or adjusting pH levels. These pouches are designed to be dissolved directly into water, providing a fresh 1X solution instantly. This "first-in-class" solution reduces preparation time and eliminates the risk of "human error" during buffer formulation.

Fast Running Formulations

For laboratories requiring rapid results, we offer specialized Fast Running powder mixes. These are specifically engineered for higher voltage DNA electrophoresis, allowing you to complete your runs faster without generating excessive heat that could melt your gels.

Key Benefits of Our Buffer Selection

Comprehensive Molecular Biology Support

Stellar Scientific provides a diverse range of QuickSilver™ pouches to cover every step of your molecular biology and protein chemistry workflows, including:

  • TAE & TBE: For nucleic acid separation.

  • TGS (Tris-Glycine-SDS): Pre-measured for seamless SDS-PAGE protein analysis.

  • PBS, PBST, TBS, & TBST: Reliable pre-made pouches for essential washing and blotting applications.

Purity and Research Integrity

By using pre-measured pouches, you ensure consistent ionic strength and pH for every run. This reliability is the foundation of sharp, reproducible bands and clear experimental data, allowing you to focus on your next breakthrough rather than your buffer chemistry.

Flexible and Cost-Effective Formats

Whether you prefer the simplicity of pouches or require concentrated liquid stocks, we provide options to fit your lab's scale. Our TBE Buffer 10X Solution (1 Liter) offers high-volume flexibility, while our 100/CS and 50/CS pouch cases provide the ultimate convenience for high-throughput environments.

Key Buying Considerations for Electrophoresis Buffers

1. Application Type

Match your buffer to your specific analysis. Use TAE for larger DNA fragments or cloning, TBE for smaller fragments and high resolution, and TGS for standard protein electrophoresis.

2. Convenience vs. Volume

Our pre-made pouches (available in 100/CS or 50/CS) are ideal for benchtop convenience and preventing contamination. For very high-volume applications, a 10X liquid concentrate may offer the scalability your facility needs.

3. Voltage Requirements

If your protocol requires high-voltage separation to save time, ensure you select our Fast Running powder mixes to prevent gel deformation and maintain sample integrity throughout the run.

Frequently Asked Questions

What buffers are available in the QuickSilver™ pouch line?

We offer a full suite of pre-measured 1X pouches, including PBST, TBS, TBST, TAE, PBS, and TGS (Tris-Glycine-SDS). These are typically sold in cases of 50 or 100 pouches for maximum lab efficiency.

How do I prepare a buffer using a QuickSilver™ pouch?

Preparation is simple: empty the contents of one pouch into a liter of distilled or deionized water, stir until dissolved, and your 1X buffer is ready for use. No pH adjustment is necessary.

Can I use the Fast Running powder for standard DNA gels?

Yes. While it is optimized for high-voltage runs, it can be used for standard electrophoresis to provide excellent resolution while maintaining a cooler gel temperature than traditional TAE.

What is the shelf life of pre-measured pouches?

Because the buffers are stored in powder form within sealed pouches, they have a significantly longer shelf life and are less prone to microbial growth compared to carboys of pre-mixed liquid buffers.
