CXCR4 expression and Cu-AMD3100 binding by CHO cells. a Histograms of non-transfected (dashed line) and transfected (solid line) cells stained with anti-CXCR4-PE and compared with transfected cells stained with an isotype control antibody (solid gray fill) by using flow cytometry. b Competition binding of 125I-CXCL12 with unlabeled Cu-AMD3100. Data points are from triplicate samples from two experiments, and error is standard deviation.
