Introduction to Polyacrylamide Gels | Bio-Rad

Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Polyacrylamide Gel Electrophoresis. Polyacrylamide gels are made by chemical polymerization of a mixture of acrylamide and bisacrylamide (a cross-linker) in the presence of a catalyst and an initiator of the polymerization reaction. The porosity of the gel is determined by the relative concentration of acrylamide to cross-linker and by the

Polyacrylamide Gel Electrophoresis, How It Works, Technique

Polyacrylamide Gel Electrophoresis (PAGE) When electrophoresis is performed in acrylamide or agarose gels, the gel serves as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the gel’s pore structure allows smaller proteins to travel more rapidly than larger proteins (Figure 2.1).

The principle and method of polyacrylamide gel

Polymerized acrylamide (polyacrylamide) forms a mesh-like matrix suitable for the separation of proteins of typical size. The strength of the gel allows easy handling. Polyacrylamide gel electrophoresis of SDS-treated proteins allows researchers to separate proteins based on their length in an easy, inexpensive, and relatively accurate manner.
