  • Title: Novel cross-linked homogeneous polyacrylamide gels with improved separation properties: investigation of the cross-linker functionality.
    Author: Patras G, Qiao GG, Solomon DH.
    Journal: Electrophoresis; 2001 Dec; 22(20):4303-10. PubMed ID: 11824594.
    Abstract:
    Polyacrylamide (PAAm) gels were synthesized using cross-linkers with their potential functionality (twice the number of double bonds of a cross-linker) varying from six to sixteen. Improved electrophoretic separation and highly desirable porosity and sieving properties were observed for most of the PAAm gels containing novel cross-linkers. An increase in the potential functionality of cross-linkers used in PAAm gels was an important factor, influencing the pore size and pore size distribution of the network.
