Which agarose do I need?

Select agarose based on fragment size and application

Gels made of different agaroses vary in sieving properties, gel strength, and melting temperatures. Downstream applications may require Genetic Technology Grade agarose. Select your agarose by fragment size, application and quality

Select agarose based on technique

Agarose gel electrophoresis techniques such as DNA recovery from gels, in-gel reactions, Southern or Northern Blotting require specific agarose properties. Use this guide to find the agarose that matches your technique

Define agarose concentration by fragment size

The pore size of an agarose gel influences its separation capabilities. Smaller pores better separate smaller nucleic acid fragments. Increasing agarose concentrations result in smaller pores. Select optimal gel concentrations for your application.

Helpful information and
additional resources

For many years we have supplied the research community with high quality agarose gel electrophoresis products and enabled nucleic acid separation, detection, and recovery. Those years of experience led to the development of The Sourcebook – “everything you could possibly want to know about agarose gel electrophoresis.”

Section II of our SourceBook provides the following valuable information on how to prepare gels for agarose gel electrophoresis:
 

- Agarose and Compatible Techniques (page 76)

- Agarose Types (page 77)

- Agarose Analytical Specifications (page 79)

- Suggested Agarose Concentrations & Dye Migration Information (page 80)

- Buffers for Electrophoresis (page 81)

- Dissolving Agarose (page 83)

- Casting Agarose Gels (page 85)

A rich history of agarose expertise

Lonza is one of the very few agarose suppliers in the world with experience in development, manufacture, quality control and distribution of agarose. Since the 1960’s, our agarose products have been supplied under the names Cambrex, Biowhittaker, FMC and Marine Colloids. In 2007, with the acquisition of the agarose manufacturing facility from Cambrex, Lonza became a leading innovator and trusted supplier of agarose and precast gels. Since then, we have been marketing our agarose gel electrophoresis product brands, including SeaKem®, NuSieve®, and MetaPhor®, with Lonza’s reputation for high quality and reliable performance.

With over 50 years of experience providing fast, reliable agarose gel electrophoresis and analysis of nucleic acids and proteins, Lonza offers a complete range of specialized agaroses. Bringing a strong history of innovation and reliability to your most important research, our well-known brands set the standard for quality in nucleic and protein agarose gel electrophoresis.
