Abstract. Changes in the reserve proteins of soybean seeds (Glycine max) were investigated by the techniques of disc eleotrophoresis and disc immunoelectrophoresis. Three different antisera were used in these studies, an anti-whole soybean extraot serum 129, an anti-llS soybean protein monos8pecific serum 102, and an anti-7S soybean protein monospeoific serum 132. At least 6 antigenically distinct components were found to be present in the proteins of the isolated soybean protein bodies. These components are metalbolized at different rates during germination. The major soybean protein (11S comnponent) is found to be present even after 16 days of germination, whereas the 78 component disappears after the ninth day. Histochemical observations of ootyledon sections during germination are also reported.
