摘要

The cyclic oligopeptides bacitracin A and gramicidin-S were immobilized on epoxy-, tosyloxy- and halogenoaklyl-activated silicas. The sorbents obtained were tested for affinity binding of proteinases. The effects of spacer length, ligand loading and the character of ligand attachment (one- or poly-site) on the biospecific characteristics have been studied.
