A type of column chromatography
which is used to separate antigen
s from a mixture. The technique
makes use of an immunoadsorbent
-- a solid, stationary matrix
within the column to which antibodies
are attached. As the mixture flows through the column, the antibodies bind to the antigens; the antigens thus stay within the column while the rest of the mixture continues through to the end. The antigens are then flushed out of the column and collected separately.
