The techniques of electron spin resonance (ESR) and fluorescence spectroscopy have been used to study the interaction of a spin-labeled analogue of adenine, N6-(2,2,6,6-tetramethyl-1-oxypiperidin-4-yl)adenine (I), with several plant lectins. While most adenine derivatives enhanced lectin-induced
An N-acetyl-D-galactosamine-specific lectin has been isolated from the two seed forms of the hog peanut (Amphicarpaea bracteata) using an affinity support containing the synthetic type A blood group trisaccharide alpha-D-GalNAc-(1,3)-[alpha-L-Fuc-(1,2)]-beta-D-Gal (Synsorb A). The affinity-purified
