Difference Between Agarose and Polyacrylamide

An agarose–acrylamide composite native gel system

Using the agarose–polyacrylamide composite native gel system we have found a way to circumvent the operational difficulties associated with low-percentage (⩽2%) polyacrylamide gels The CNG is capable of providing a sturdy physical support at very low polyacrylamide percentages (e g 1 5%) with satisfactory electrophoretic performance

Difference Between Acrylamide and Polyacrylamide

Key Difference – Acrylamide vs Polyacrylamide Acrylamide and Polyacrylamide are two amide molecules but acrylamide is a single molecule and Polyacrylamide is a polymer (a large molecule which is formed by monomers) which is produced from the monomers (a molecule that can be bonded to other identical molecules to form a polymer) of acrylamide In other words the key difference between

Agarose gel electrophoresis (basic method)

Agarose gel electrophoresis is the easiest and commonest way of separating and analyzing DNA The purpose of the gel might be to look at the DNA to quantify it or to isolate a particular band The DNA is visualised in the gel by addition of ethidium bromide which is mutagenic or less-toxic proprietary dyes such as GelRed GelGreen and SYBR Safe

What is agarose used for? As a gelling agent agarose is used in: Electrophoresis: Agarose is used for a wide range of electrophoresis applications including separation of nucleic acids immunoelectrophoresis (IEP) and isoelectric focusing Unlike polyacrylamide the consistency of the gels is more solid (but also less elastic) 6 Immunodiffusion: Agarose is used as the solid gel matrix
