Abstract
A system and method for isolating and purifying complexes of biologically active compounds. The inventive system and method utilize a centrifugal filtration device employing a membrane having ligands that preferentially bind a biologically active compound. An advantage of the invention is that purifications of, e.g., immune complexes, which heretofore took up to five days to carry out, may now be done in as little as two hours.
