Methods for purifying sialic acid-specific antibodies and composition comprising affinity-purified antibodies

摘要

The present invention relates to a method of purifying sialic acid-specific antibodies, comprising the steps of:
(a) preparing antibodies to sialic acids;
(b) contacting the antibodies from step (a) with a first solid phase to which a sialic having a side chain has been attached; and
(c) contacting the antibodies that bound to the first solid phase with a second solid phase to which the sialic acid without the side chain has been attached.
