clear native polyacrylamide gel electrophoresis quantitative preparative native continuous polyacrylamide gel electrophoresis 2009-08-19T11:46:47Z https://orcid.org/0000-0001-5985-7429 A separation method where metalloprotein molecules move at different speeds, in a buffer with pH 10, according to their charge and frictional forces in a separation medium consisting of polyacrylamide gel, across which an electric field is applied. This method does not use a dye to transfer charge to the protein molecules and the concentration of metal atoms from the metallproteins is determined by ICP-MS. CHMO:0002278
