QPNC-PAGE

QPNC-PAGE, or Quantitative Preparative Native Continuous Polyacrylamide Gel Electrophoresis, is a bioanalytical, one-dimensional, high-resolution and high-precision technique applied in biochemistry and bioinorganic chemistry to separate proteins quantitatively by isoelectric point and by continuous elution from a gel column.

This standardized variant of native gel electrophoresis and subset of preparative polyacrylamide gel electrophoresis is used by biologists to resolve macromolecules in solution with high recovery, for example, into active or native metalloproteins in biological samples or properly and improperly folded metal cofactor-containing proteins or protein isoforms in complex protein mixtures.
