For example, membranes with high EGFR expressions were adopted as the stationary phase of cellular membrane affinity chromatography for ligand screening,[12] and tumor cell membranes with tumor‐homing membrane proteins have helped in the construction of actively targeting delivery systems.[13] Hence, cell membranes with appropriate receptor levels see prospects as prebinding modules on antibody or antibody‐mediated drug targeting, which could not be substituted by low‐expression receptors at nontarget sites yet could competitively dissociate on the target sites. The gene discussed is EGFR; the disease is neoplasm.
