Figure 3.
Measurement of β-arrestin levels after incubation with CXCL12 and various carriers. Negative Control represents cells that were not incubated with CXCL12, Plerixafor, or carriers. Positive Control represents cells incubated only with CXCL12. Plerixafor-immobilized Carriers represents cells incubated with 1 μg/mL targeted carriers. Control Carriers represents cells incubated with 1 μg/mL unmodified carriers. Free Plerixafor represents cells incubated with 1 μM Plerixafor. *** denotes p < 0.001 compared to the positive control.
