  • What is sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE)?
  • Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is commonly used to obtain high resolution separation of complex mixtures of proteins. The method initially denatures the proteins that will undergo electrophoresis.
  • What is SDS & polyacrylamide gel used for?
  • This is often used to separate proteins with molecular masses ranging from 5 to 250kDa. The combination of SDS and Polyacrylamide gel reduces the influence of structure and charge, allowing proteins to be sorted entirely on the basis of their molecular weights.
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
  • What is a 15% polyacrylamide gel used for?
  • Gels of 15% polyacrylamide are therefore useful for separating proteins in the range of 100,000–10,000. However, a protein of 150,000 for example, would be unable to enter a 15% gel. In this case, a larger-pored gel (e.g., a 10% or even 7.5% gel) would be used so that the protein could now enter the gel, and be stained and identified.
