AFFINITY CHROMATOGRAPHY ADSORBENTS

摘要

A process for the preparation of an affinity chromatography absorbent consists of contacting an affinity chromatography matrix with gelatin or collagen and cross-linking the gelatin or collagen within the matrix with glutaraldehyde. The matrix is in the form of pre-formed, preferably cross- linked, beads. Once formed the absorbents may be used in the affinity chromatographic separation of certain naturally occurring proteins in particular fibronectin.
