Competitive
CXCR4 binding activity of DV1, SDF-1α, AMD3100, and IT1t in
FITC-DV1- and 12G5 Ab-based competitive binding assays. (A) The competitive
capacities of DV1 (blue asterisks) and SDF-1α (maroon times
signs) in the FITC-DV1-based assay were comparable to those of DV1
(red circles) and SDF-1α (black triangles) in the 12G5 Ab-based
assay, for binding CXCR4. (B) The competitive capacities of AMD3100
(black asterisks) and IT1t (red times signs) in the FITC-DV1-based
assay were comparable to those of AMD3100 (black triangles) and IT1t
(black diamonds) in the 12G5 Ab-based assay, for binding CXCR4. Means
± the standard deviation; n = 3 independent
experiments.
