NEW PROCESS FOR THE DISRUPTION OF BACTERIA CELLS CONTAINING RECOMBINANT POLYPEPTIDES

摘要

1. Process for isolating a polypeptide prepared by recombinant methods from bacterial cells, characterised in that bacterial cells containing a polypeptide prepared by genetic engineering, these cells being suspended in an aqueous acid at a pH of from 2.0 to 4.0, are mechanically destroyed by shear forces and subsequently the polypeptide now present in the resulting suspension is separated and further purified by known methods.
