  • What is a polyacrylamide hydrogel?
  • verviewPolyacrylamide is synthetic polymer derived rom acrylamide monomer. Polyacrylamide is crosslinked polymer of acrylamide In the cross-linked form, it is highly water-absorbent, forming a soft gel. Generally, polyacrylamide hydrogels results from polymerization of acrylamide with a suitable bifunctional Cr
  • How are polyacrylamide gels prepared?
  • 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).
  • What is orange G used for?
  • It is often combined with other yellow dyes and used to stain erythrocytes in the trichrome methods. Orange G can be used as an electrophoretic color marker to monitor the process of agarose gel electrophoresis, running approximately at the size of a 50 Base pair (bp) DNA molecule, and polyacrylamide gel electrophoresis.
  • How are polyacrylamide gels characterized?
  • Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.
