ABSTRACT:
A process for purifying an antibody is provided. In this process, a mixture containing the antibody and a contaminant is subjected to low pH hydrophobic interaction chromatography (LPHIC) at low salt concentration. The antibody is eluted from the column in the fraction which does not bind thereto. This process can be preceded and followed by other purification steps.
