Figure 3. Specificity of adenovirus immobilization on PPX-NH2 treated surfaces using the VBABM method.

Figure 3

Biotin was conjugated on PPX-NH2 deposited PCL surfaces to immobilize avidin, and then biotinylated adenoviral vectors in different concentrations were placed on the surfaces (dashed line). The same biotinylated virus solutions were placed on non-modified PCL surfaces as the control group (solid line). The bound adenovirus was determined by ELISA to investigate if these modified surfaces may specifically immobilize virus.
