title: New support for the large-scale purification of proteins.
abstract: We propose a new affinity sorbent, matrix-linked histidine, for the large-scale purification of proteins. A variety of proteins and certain peptides, each distinct from the other, were purified. Immunoglobulin G from human placenta was chosen for a detailed study concerning the effects of coupling, spacer-arm and other parameters. Multiple interactions such as charge-transfer and other ionic reactions have been suggested to be responsible for the interactions between proteins and ligand.
