Wisteria floribunda (Japanese wisteria) Lectin (WFA/WFL)

Category: Tag:

Wisteria floribunda agglutinin or lectin (WFA/WFL) is isolated from Japanese Wisteria seeds. It is a glycoprotein with a molecular weight of 116, 000 and is composed of four subunits. It has an isoelectric point between pH 5.2 and pH 5.8. This lectin is not blood group specific although it does react stronger with human type A1 cells over A2, B, or O cells. The presence of a sialic acid residue may explain the lectins lack of reactivity. The increased reactivity of neuraminidase treated erythrocytes with WFA supports this conclusion.WFA contains a strong hemagglutinin activity and is a potent mitogen, both strongly inhibited by GalNAc, although mitogenic activity is also inhibited by N, N-diacetylchitobiose. Isolated by use of salt precipitation, ion-exchange chromatography, and gel filtration. See other WFA/WFL conjugates.This product comes in a lyophilized form and is stored at -20° C
