Summary
The seed of lima beans contains a hemagglutinating substance (lectin) of value in immunochemical research and in typing human bloods. During the early growth of the seed, this substance increases rapidly in comparison with dry weight of the seed, but subsequently increases in proportion to dry weight. During germination of the seed and growth of the seedling, lectin decreases rapidly but small quantities may be detected in various plant parts. Although the activity of the substance may be inhibited by N-acetyl-D-galactosamine, a reaction reversible by dialysis, the titre was not increased nor was the specificity changed by dialysis of the fresh extract.
