Polypeptide ligation occurs during post-translational modification of concanavalin A
Lectins are proteins with multivalent carbohydrate-binding sites, which confer the ability to agglutinate. The seeds of legumes are particularly rich in lectins, for example, concanavalin A (Con A)Expand

Development and mechanical characterization of solvent-cast polymeric films as potential drug delivery systems to mucosal surfaces
Solvent-cast films from three polymers, carboxymethylcellulose (CMC), sodium alginate (SA), and xanthan gum, were prepared by drying the polymeric gels in air. Three methods, (a) passive hydration,Expand
