Oligomeric status of CXCR4 on the cell surface treated and untreated by CPZ. The experiments were carried out using the stably transfected T-Rex-HEK293 cells under resting state (without SDF-1α stimulation) and cells at different induction times were characterized by single-molecule imaging respectively. (A) Relative amount of monomer, dimer and oligomer of CXCR4-EGFP on the cell surface at induction times of 1, 2, 4, and 8 h without CPZ treatment; (B) Relative amount of monomer, dimer and oligomer of CXCR4-EGFP on the cell surface at induction times of 1, 2, 4, and 8 h with CPZ treatment.
