  • Method of visualizing proteins bound to protein-binding membranes
    Patent number: 7575858
    Abstract: A method of visualizing proteins bound to a protein-binding membrane is provided herein, comprising reacting proteins bound to protein-binding membranes with a compound of formula (I) wherein Ra, R1, R2, R3, R4, M, n, and m are as defined herein.
    Type: Grant
    Filed: September 9, 2003
    Date of Patent: August 18, 2009
    Assignee: Temple University—Of The Commonwealth System of Higher Education
    Inventors: Christopher R. Yonan, Frank N. Chang
  • System and methods for electrophoretic separation of proteins on protein binding membranes
    Patent number: 7326326
    Abstract: Proteins can be rapidly separated to a high degree of resolution by electrophoresis on polymeric membranes that have high protein binding capacity. The electrophoretic separation is carried out in a low conductivity, water-miscible organic solvent buffer. The low conductivity of the organic solvent buffer minimizes heat generation, and the water-miscible nature of the organic solvent buffer permits the analysis of hydrophobic and low molecular weight proteins as well as hydrophilic proteins. When electrophoresis is conducted under non-denaturing conditions, it allows the detection of enzymatic activities, protein-protein interactions and protein-ligand interactions.
