High Quality Content by WIKIPEDIA articles! QPNC-PAGE, or quantitative preparative native continuous polyacrylamide gel electrophoresis, is a high-resolution technique applied in biochemistry and bioinorganic chemistry to separate proteins by isoelectric point. This new and inventive variant of gel electrophoresis is used by biologists to isolate active or native metalloproteins in biological samples and to resolve properly and improperly folded metal cofactor-containing proteins in complex protein mixtures. The QPNC-PAGE procedure is accomplished in a special electrophoresis chamber (see External links) for separating charged biomolecules. Due to the specific properties of the prepared gel and electrophoresis buffer solution (which is basic and contains Tris-HCl and NaN3), most proteins of a biological system are charged negatively in the solution, and will migrate from the cathode to the anode due to the electric field. Although the pH value (10.00) of the electrophoresis buffer does not correspond to a physiological pH value within a cell or tissue type, the protein isomers are eluted continuously by a physiological buffer solution and isolated in different fractions.
