Methods are described for the preparation of hydrazido-alkyl agarose derivatives useful for purification of biologically active compounds by affinity chromatography. The hydrazido-agarose permits the attachment of different functional groups through non-charged extended hydrocarbon spacers. These spacers place the functional groups at varying distances from the gel matrix. The different functional groups introduced, enable the coupling of ligands to agarose through their amino, carboxyl, imidazole, phenol and thiol groups.

The problem of leakage of functional groups when attached via monovalent coupled spacers was overcome by coupling polyglutamic acid hydrazide or linear polyacrylic hydrazide to agarose. The high stability obtained results from the multipoint attachment of the polymers to agarose. The polyhydrazidoagarose was also used for further derivatization.
