  • What is two-dimensional polyacrylamide gel electrophoresis?
  • Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) separates proteins by their iso-electric points (IEPs) and electro-phoretic mobilities ( 1 ). In the first dimension, a sample is applied to an iso-electric focusing (IEF) acrylamide gel. Within this the con stituent proteins migrate through a pH gradient until they reach their IEPs.
  • What is blue native polyacrylamide gel electrophoresis?
  • Blue-Native polyacrylamide gel electrophoresis (Blue Native PAGE) was originally introduced by Schagger and von Jagow as a technique for separating enzymatically active membrane protein complexes under mild condition .
  • How do I use a tube gel for second dimension electrophoresis?
  • The tube gels can either be used immediately for second dimension electrophoresis or stored at -70°C until they are required. Leave the tube gels in the equilibration buffer. The general procedure will be the same for most pieces of equipment. 1. Clean the glass plates with alcohol. Assemble the glass plates, spacers ( see Note 12 ), and clamps.
  • How does acrylamide gel work?
  • In the first dimension, a sample is applied to an iso-electric focusing (IEF) acrylamide gel. Within this the con stituent proteins migrate through a pH gradient until they reach their IEPs. A protein’s IEP is the pH value where it has no net charge. This is as a result of the positively and negatively charged amino acids cancelling each other.
