Agarose is a linear polysaccharide used for gel mediums. Tm (melting temp) is about 85 C.
No, agarose is not a protein. It is a polysaccharide, which is a type of carbohydrate.
The main difference between a 2% and a 3% agarose gel is the concentration of agarose in the gel. A 3% agarose gel will have a higher agarose concentration, resulting in a higher resolving power for separating larger DNA fragments compared to a 2% agarose gel. However, a higher percentage agarose gel may also have a tighter mesh size, making it harder for larger DNA fragments to migrate through the gel.
An agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar and used to make gels.
Agarose is used in gel electrophoresis as a medium to separate DNA fragments based on their size. When an electric current is passed through the agarose gel, DNA molecules move through it at different speeds, allowing for separation by size. Agarose forms a matrix that acts as a sieve, slowing down larger DNA fragments more than smaller ones.

Agarose solution is a gel-like substance used in molecular biology and biochemistry for techniques like agarose gel electrophoresis. It is derived from seaweed and forms a matrix in which DNA, RNA, and proteins can be separated based on size. The concentration of agarose in the solution determines the size range of molecules that can be effectively separated.
Agarose gel electrophoresis is suitable for ALL DNA.
Try increasing the concentration of agarose in your gel mixture or extending the cooling time in the refrigerator. You can also check if the agarose powder is expired or if there was an error in the preparation process. If the issue persists, consider using a different brand or batch of agarose.
Agarose gel electrophoresis separates biomolecules based on size and charge, while SDS-PAGE separates based on size and mass. Agarose gel is used for larger molecules like DNA and RNA, while SDS-PAGE is used for proteins. Agarose gel uses a gel made from agarose, while SDS-PAGE uses a gel made from polyacrylamide.
