Immunochemical crossreactivity between globulins from buckwheat and indigo seeds.

Immunochemical relationships between salt-soluble proteins (albumins plus globulins) from buckwheat and indigo seeds were shown by immunoblot and immunodiffusion analyses using rabbit antisera raised against buckwheat globulins. These antigenic crossreactivities were roughly consistent with their polypeptide components judged by two-dimensional electrophoresis and SDS-PAGE analyses.
