- What is polyacrylamide gel electrophoresis?
- Different separation media and mechanisms allow subsets of these molecules to be separated more effectively by exploiting their physical characteristics. For proteins in particular, polyacrylamide gel electrophoresis (PAGE) is often the technique of choice. What is polyacrylamide gel electrophoresis and what is protein electrophoresis?
- How does a polyacrylamide gel separate analytes?
- The basic principle of PAGE is to separate analytes by passing them through the pores of a polyacrylamide gel using an electric current. To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS).
- What is polyacrylamide gel?
- Related Topics: Protein Standards, Buffer Systems and Gel Chemistries, and Handcasting Polyacrylamide Gels. Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide.
- What does %t mean in polyacrylamide gel?
- %T indicates the relative pore size of the resulting polyacrylamide gel: higher %T refers to a larger polymer-to-water ratio and on average smaller pores. The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker.
