Preparation of affinity sorbents based on monoclonal antibodies to cottonplant membrane proteins

An immunosorbent has been obtained by conjugating mcABs 2C8.C7 to membrane proteins from cotton seedlings with BrCN-Sepharose 4B. As a result of the affinity chromatography of the total lectin-like proteins of the cotton plant on this sorbent, two fractions of polypeptides have been isolated, and these have been subjected to electrophoretic analysis.
