Figure 6. Flow cytometry analysis of CXCL12 interaction with cell surface GAGs.
CHO-K1 parental cells (squares) or HS-deficient CHO-pgsD677 cells (triangles) were incubated with the indicated concentrations of CXCL12 α (open symbols) or γ (close symbols) and, after extensive washing to remove free chemokine, were labelled with K15C mAb and analyzed by flow cytometrey.
