Abstract
Magnetizable, porous particles are prepared by contacting a first portion of porous particles with a suspension comprised of magnetite particles, coated with a dispersing agent, and water, removing and discarding the first portion of porous particles, contacting the suspension with a second portion of porous particles, and separating the second portion of porous particles from the suspension. The magnetizable, second portion of porous particles may be ion exchange resin particles used in a magnetically stabilized fluidized bed to isolate proteins from cell lysate.
