  • What is polyacrylamide gel electrophoresis?
  • Polyacrylamide gel electrophoresis, popularly known by its acronym PAGE is an analytical technique which is based on the principle of migration of charged particles under the influence of electrical field. The main purpose of this technique in analytical chemistry is to separate the mixture of protein or nucleic acid based on their size.
  • What is the best stain for detecting proteins in polyacrylamide gels?
  • Improved staining of proteins in polyacrylamide gels including isoelectric focusing gels with clear background at nanogram sensitivity using Coomassie Brilliant Blue G-250 and R-250. Electrophoresis 9, 255–262. Oakley BR et al. (1980). A simplified ultrasensitive silver stain for detecting proteins in polyacrylamide gels. Anal Biochem 105, 361–363.
  • Can polyacrylamide be used for protein separation?
  • For protein separation, virtually all methods use polyacrylamide as an anticonvective, sieving matrix covering a protein size range of 5–250 kD. Some less common applications such as immunoelectrophoresis and the separation of large proteins or protein complexes >300 kD rely on the larger pore sizes of agarose gels.
  • What is a low acrylamide Pag?
  • PAGs of low acrylamide concentration (<4%) are generally used as separating matrix where proteins can move freely without any sieving effect/frictional force. In these gels, gradually changing pH gradient is established by adding ampholytes of different pH ranges.
