  • Introduction to Polyacrylamide Gels | LSR | Bio-Rad

    A standard gel used for the separation of proteins generally contains about 7.5% polyacrylamide. Pore size in polyacrylamide gels is determined with the values of % T [total polyacrylamide percentage (w/v)] and % Cbis [the ratio of bis to monomer (w/w)] using the following formulae: % T = Acrylamide (g) + Bis (g) Volume (mL) × 100

  • Polyacrylamide Gel - an overview | ScienceDirect

    The Laemmli SDS-PAGE system is a discontinuous gel with an upper stacking gel and lower resolving gel that have different pH values and polyacrylamide concentrations. The upper stacking gel has a lower percentage of polyacrylamide allowing proteins to move through quickly and ‘stack’ into a tight band before entering into the higher percentage polyacrylamide resolving gel for separation.
