Polyacrylamide gel electrophoresis - Wikipedia

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a method of separating molecules based on the difference of their molecular weight. At the pH at which gel electrophoresis is carried out the SDS molecules are negatively charged and bind to proteins in a set ratio, approximately one molecule of SDS for every 2 amino acids.

SDS-PAGE - Wikipedia

SDS-PAGE ( sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.

Introduction to SDS-PAGE - Separation of Proteins Based on Size

Introduction to SDS-PAGE - Separation of Proteins Based on Size Polyacrylamide gels are formed by the reaction of acrylamide and bis-acrylamide ( N,N ’-methylenebisacrylamide) that results in highly cross-linked gel matrix. The gel acts as a sieve through which the proteins move in response to the electric field.

SDS‐Polyacrylamide Gel Electrophoresis (SDS‐PAGE) of Proteins

SDS Page Gel Electrophoresis. PAGE. Polyacrylamide gel electrophoresis (PAGE) is probably the most common analytical technique used to separate and characterize proteins. A solution of acrylamide and bisacrylamide is polymerized. Acrylamide alone forms linear polymers. The bisacrylamide introduces crosslinks between polyacrylamide chains.
