  • Title: Isolation and some properties of mammalian hepatic membrane lectins.
    Author: Ali N, Salahuddin A.
    Journal: FEBS Lett; 1989 Mar 27; 246(1-2):163-5. PubMed ID: 2468526.
    Abstract:
    Membrane lectins were isolated from sheep, goat, and buffalo liver by chromatography on an asialofetuin (ASF)-Sepharose 4B column. The lectins moved as a single protein band in SDS-PAGE with molecular masses of 42, 54 and 50 kDa, respectively, for sheep, goat and buffalo lectins. The molecular masses remained unchanged in 0.2 M 2-mercaptoethanol. As judged from the inhibition of binding of the lectin to ASF gel, the three lectins were beta-galactoside-specific. Sheep, goat and buffalo lectins were found to be sialoglycoproteins containing 18.6, 27 and 38.8 mol/mol lectin of neutral hexose, respectively; the corresponding values for the sialic acid content being 5.3, 8.7 and 11.8 mol/mol lectin. Thus goat and buffalo lectins are physico-chemically different from many mammalian hepatic lectins described so far.
