QPNC-PAGE

QPNC-PAGE, or Quantitative Preparative Native Continuous Polyacrylamide Gel Electrophoresis, is a bioanalytical, high-resolution and high-precision zone electrophoresis technique applied in biochemistry and bioinorganic chemistry to separate proteins or protein isoforms by isoelectric point and by continuous elution from a gel column for further characterization.

This standardized 1-D hybrid variant of native gel electrophoresis and preparative polyacrylamide gel electrophoresis is used to quantitatively resolve physiological concentrations of macromolecules with high recovery, for example, into active or native metalloproteins in biological samples or into properly and improperly folded metal cofactor-containing proteins in complex protein mixtures.
