Different amounts of wheat germ agglutinin were immobilized to agarose
gel, previously activated by different amounts of the coupling agent
divinyl sulfone. The effectiveness of these affinity sorbents was char
acterized by specific binding of ovomucoid with the gel. These studies
revealed the formation of clear optima in binding capacity of the aff
inity gel, depending on conditions of its synthesis. The ratio between
the concentration of the coupling agent and immobilized lectin were f
ound to be crucial for optimization of binding properties of the affin
ity sorbent.
