PROTEIN SEPARATION FROM A PROTEIN MIXTURE

摘要

A process for separating a protein from a sample containing a mixture of proteins is disclosed. The process comprises forming an aqueous combination comprising the sample and an ion exchange material at a pH which is less than the pI of a first fraction of the proteins in the aqueous dispersion but greater than the pI of a second fraction of the proteins in the aqueous dispersion. This process requires no expensive, specialized instrumentation, can be quickly performed, and is carried out in non-denaturing conditions, allowing for the separated proteins to be further studied. The process may be used to remove albumin from a biological sample.
