Fluorescence microscopy analysis of FGF2 binding to cells remodeled with various neoPGs. Cells treated with AF488-labeled neoPGs display green fluorescence. Cells remodeled with FGF2-binding neoPGs (11D) show significant fluorescence compared to non-binding neoPGs (11A and 11N) upon treatment with exogenous FGF2 and immunostaining with anti-FGF2 and AF555-labeled secondary antibody.
