Development and Distribution of Dolichos biflorus Lectin as Measured by Radioimmunoassay 1

Abstract

A radioimmunoassay, capable of detecting the Dolichos biflorus lectin at concentrations as low as 400 ng/ml, was developed and used to follow the distribution of this lectin in the plant during its life cycle.

The lectin was first detected in the seeds of the plant 27 days after flowering and rapidly attained the high level of lectin present in the mature seed. The lectin content of the plant is highest in the seeds and cotyledons and decreases as the storage materials of the cotyledons decrease.

A low but measurable amount of material that reacts with antibodies to the seed lectin was detected in the leaves, stems, and pods of the plant. This material gives a precipitin band of only partial identity to the seed lectin when tested in immunodiffusion against antiserum to the seed lectin.

No lectin was detected by the radioimmunoassay in the roots of the plant at any stage of development.
