Concanavalin A (Con A) was spontaneously adsorbed on polymyxin B surface. This peptide-lectin interaction was strong, K(D)=1.9 x 10(-10), based predominantly on creation of hydrophobic bonds, and was completely reversible. Concanavalin A on polymyxin B (PmB) retained higher binding capacity for yeast mannan, compared with covalently immobilized lectin. Kinetics of mannan-concanavalin A interaction were significantly different in dependence on type of concanavalin A immobilization.
