Balding and Gold599 studied the agglutination of various, red bloodcell types by extracts of Sophora japonica seeds from varied geographical sources. Whereas a purified lectin sample from R. D. Poretz (seeds from a supplier in the United States) and lectin from Japanese seeds did not agglutinate O cells, a sample from Portugal did. All three lectin...

The addition of specific sugars to solutions of several lectins induces u.v. difference spectra. Difference spectra for Lens culinaris, Sophora japonica, Solamm tuberosum lectins, and wheat germ agglutinin have peaks characteristic of the L-tryptophan residue, whereas that of Arachis hypogaea agglutinin has peaks characteristic of L-tyro ine residues. The binding constants for the lectins with specific sugars may be determined from the intensities of the difference spectra. Lectins may be used for the differentiation of serum enzymes. Lectins from... 

Lectins from soybean, Wistaria floribunda, Bauhinia purpurea var. alba, and Sophora japonica were bound by acid-treated Sepharose 6B, whereas those from lima bean, Dolichos biflorus, and kidney bean were not. The binding of lectins by acid-treated Sepharose was affected by temperature and pH.
