Why agarose gel electrophoresis is not used for protein analysis?
Agarose gel electrophoresis is primarily used for separating and analyzing nucleic acids based on their size, as it provides good resolution for DNA and RNA molecules. However, proteins have different properties (charge, size, and shape) compared to nucleic acids, making agarose gel less suitable for protein analysis. For protein analysis, techniques like SDS-PAGE and isoelectric focusing are commonly used, as they are designed specifically for separating proteins based on their size, charge, and isoelectric point.
What is role of agarose of electrophoresis?
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.
What is differences between agar and agarose?
Agarose is made from agarose, a polysaccharide from see weeds. Polyacrylamide is made from the synthetic polymerization of acrylamide, which in its monomeric form is a neurotoxin. Based on these structural differences, it could be said that agarose gels have larger 'pores' than polyacrylamide gels meaning that large particles can move more easily in agarose gels since the agarose polymers are larger and pack less densely then an equivalent amount of polyacrylamide. Therefore, agarose is generally used for the electrophoresis of large molecules such as DNA and RNA or speedy separation (low resolution) of small molecules such as proteins. Polyacrylamide is used for the high resolution electrophoresis of small molecules such as proteins.
what is the gel in Gel Electrophoresis?
The gel in gel electrophoresis is typically made of agarose or polyacrylamide. It acts as a matrix to separate DNA, RNA, or proteins based on size and charge as an electric current passes through it. Agarose gels are commonly used for DNA analysis, while polyacrylamide gels are often used for higher resolution protein separation.
What are the differences between agarose gel electrophoresis and SDS-PAGE techniques for separating and analyzing biomolecules?
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.

What is agarose and what is the TM value of agarose?
Agarose is a linear polysaccharide used for gel mediums. Tm (melting temp) is about 85 C.

What is a difference between 2 percent and 3 percent agarose gel?
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.
What is an agarose?
An agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar and used to make gels.

In protein separation why polyacrylamite is usedwhile in separation of DNA agarose is used?
Because proteins and protein fragements are often smaller than nucleic acid molecules. You can separate proteins on a modficated agarose gel (Metaphor by Lonza) made for the separation of smaller polynucleotids. http://www.lonzabioscience.com/Content/Documents/Bioscience/MetaPhor18108-0604-7.pdf Further to the answer above. Acrylamide is used because it can be used in conditions which contain SDS (sodium dodecyl sulphate) and DTT (a reducing agent). Both are necessary to resolve proteins by size. Proteins aren't uniformly charged, which will affect the way they migrate through a gel, but by coating them in SDS this gives them a uniform negative charge. DTT and SDS both help denature the protein and break up protein-protein and protein-DNA complexes thus allowing you to resolve the individual proteins.

What Is Agarose Solution?
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.
