used to separate antigen
s from a mixture, usually as a part of immunoaffinity chromatography
. The immunoadsorbent is a solid matrix
to which antibodies
are bound; as the mixture flows through the column and past the stationary immunoadsorbent within, the antigens become attached to the antibodies and stay within the column while the rest of the mixture continues through to the end.
