Fig. 2. Real-time analysis of GP interactions with DC-SIGN. SPR sensorgrams were collected at 25 °C and a flow rate of 25 μL min^–1 and demonstrate clear interactions between linear glycopolymer P1 (Panel A), 5-arm star glycopolymer P2 (Panel B) and 8-arm star glycopolymer P3 (Panel C) and immobilized DC-SIGN extracellular domain. The sensorgram curves illustrate slow dissociation, especially of the 5-arm and 8-arm GPs during the wash phase (indicated by the guideline at 900 s).
