When it comes to DNA and protein electrophoresis, agarose is one of the most widely used reagents in molecular biology laboratories. This versatile polysaccharide, extracted from seaweed, provides the solid yet porous matrix that allows scientists to separate nucleic acids and proteins with precision. But not all agaroses are the same. Choosing the right type can make a significant difference in your experimental results.
In this article, we’ll explore the main types of agarose available, their specific characteristics, and how to select the best option for your application.
Low EEO (Electroendosmosis) Agarose
Electroendosmosis can interfere with DNA migration during electrophoresis. Low EEO agarose minimizes this effect, providing sharper bands and improved resolution.
- Recommended for analytical separation of nucleic acids.
- Reduced background ensures higher-quality images.
- Particularly useful for Southern and Northern blotting.
- Easy to prepare and handle.
- Suitable for general molecular biology applications.
- Cost-effective for laboratories with high throughput.
At Canvax, our AgaPure™ Agarose LE offers high purity and reproducibility, making it an excellent choice for standard applications.
High-Resolution Agarose
For researchers working with small DNA fragments (20–1,000 bp), high-resolution agarose is essential.
- Allows precise separation of PCR products and restriction digests.
- Offers superior clarity and minimal diffusion.
- Often used in genotyping or mutation analysis.
Canvax provides high-resolution agaroses manufactured under strict ISO standards, ensuring consistent performance across batches.
Low-Melting Point Agarose
Sometimes, DNA needs to be recovered directly from the gel. Low-melting point (LMP) agarose allows for efficient fragment isolation without damaging nucleic acids.
- Melts at lower temperatures for easy extraction.
- Compatible with enzymatic reactions (e.g., ligation, PCR).
- Ideal for cloning and downstream molecular biology applications.
Our LM agaroses are available in different formats to suit both research and teaching labs.
Agarose Tablets and Pre-Measured Formats
To simplify workflows, agarose is also available in ready-to-use tablets or pre-measured formats. These options save time and ensure consistency between preparations.
- Convenient for busy labs.
- Minimize weighing errors and contamination risks.
- Perfect for teaching labs and routine assays.

How to Choose the Right Agarose?
The choice of agarose depends on your application:
- Routine DNA analysis → Standard or Low EEO agarose.
- Small fragment separation → High-resolution agarose.
- DNA recovery → Low-melting point agarose.
- Convenience → Pre-measured tablets.
At Canvax, we manufacture a complete range of agaroses under strict ISO9001 standards, ensuring consistent performance and reliable results.
Conclusion
From basic nucleic acid separation to advanced cloning applications, there’s an agarose type tailored for every need. Selecting the right one will not only improve your results but also save valuable time in the lab.
