Agarose is a heteropolysaccharide, generally extracted from certain red algae. [1] It is a linear polymer made up of the repeating unit of agarobiose, which is a disaccharide made up of D -galactose and 3,6-anhydro- L -galactopyranose.

Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar.

Bio-Rad offers a variety of agarose powders and precast agarose gels to meet all your needs for DNA and RNA electrophoresis, including pulse field gel electrophoresis and specialty applications such as IEP and IEF.

Agarose gel electrophoresis is a powerful separation method frequently used to analyze DNA fragments generated by restriction enzymes, and it is a convenient analytical method for separating DNA fragments of varying sizes ranging from 100 bp to 25 kb.

Agarose is a polysaccharide that is isolated and purified from agar or agar-bearing marine algae (sea kelp). It is a natural polymer, made up of alternating β-D-galactose and 3,6-anhydro-L-galactose units of agarobiose in its chemical structure.

2023年4月10日 · Agarose is a highly purified polysaccharide that is isolated from agar, a gel-like substance found in red seaweed. It is a medium commonly used in molecular biology laboratories for various applications such as gel electrophoresis, DNA separation, and protein purification.

2024年5月14日 · Agarose gel electrophoresis is commonly used to resolve circular DNA with different supercoiling topology, and to resolve fragments that differ due to DNA synthesis. In addition to providing an excellent medium for fragment size analyses, agarose gels allow purification of DNA fragments.

2024年8月31日 · Agarose is a remarkable polysaccharide with a wide range of applications in molecular biology, biotechnology, and the food industry. Its unique properties, such as thermoreversibility, biocompatibility, and adjustable pore size, make it an invaluable tool for researchers and manufacturers alike.

Agarose, a polysaccharide derived from marine red algae, plays a vital role in biomedical applications because of its reversible temperature-sensitive gelling behavior, excellent mechanical properties, and high biological activity.

Agar and agarose are both polysaccharides derived from seaweed and are commonly used in laboratory settings. However, they have distinct differences in their properties and applications. Agar is a complex mixture of polysaccharides, whereas agarose is a purified form of agar.
