Figure 4. Pea stem material was sequentially extracted with hot 70% ethanol, 0.1 M EDTA and 4% KOH-0.1% NaBH4 to leave xyloglucan-cellulose cell wall ghosts . Binding of fluorescent fucose-binding lectin from Ulex europeus as visualized by fluorescence microscopy shows xyloglucan distributed over the whole wall surface. Photograph courtesy of Dr. T.

Cell division is stimulated by lectins (for a review, see Ref. 188) and by other saccharide-directed reagents, for example, sodium periodate and D-galactose oxidase after desialylation,189 but there is no evidence that it is the fucopyranosyl residues that are the specific receptors in these instances. The L-fucose-specific lectins from, for example, Lotus tetragonolobus and Ulex europeus are not mitogenic. 

Cuatrecasas (45). The Dolichos biflorus lectin was a gift from Dr. Marilynn Etzler (46). Ulex europeus and Bandeirea simplicifolia lectins were purified in our laboratory and iodinated with Nal25i (carrier-free) by Sepharose 4B-bound lactoperoxidase (47)and diazotized iodoaniline coupling (48) procedures, respectively.

Complex, blood-group-active substances have been employed as inhibitors of hemagglutination.196,693 Osawa and Matsumoto found692 inhibition of both Ulex lectins by human A-, B-, and H-active substances, whereas Lea substance and porcine, submaxillary mucin bound only to Ulex II. Chuba and coworkers693 reported that substances from porcine stomach (A-active), equine stomach (B-active), and baboon stomach (A-, B-, and O-active substances), as well as human A-, B-, and O-active substances, bound equally well to both U. europeus lectins. However, porcine, submaxillary mucin and nonsecretor saliva inhibited only Ulex II activity.

Highly porous and hydrophilic supports have been prepared by co-polymerization of A-tris(hydroxymethyl)methyl acrylamide or A-tris(hydroxymethyl)-methyl methacrylamide with acrylic monomers bearing carboxyl functions, and then treated with 4-aminophenyl a-L-fucoside using a water-soluble carbodi-imide mediator. The support was used for purification of the L-fucose-binding lectin from Ulex europeus.
