CholA-anchored glycopolymers recycle from reservoirs inside the cell to the cell surface. a) Jurkats were labeled with 5 μM AF488-capped glycopolymers. b) Jurkats loaded with CholA glycopolymers and incubated with AF647-transferrin. c) Jurkats loaded with CholA-anchored glycopolymers, then treated with anti-AF488 antibody to quench cell surface fluorescence, then allowed to incubate at the indicated temperature. d) A model for the trafficking of CholA-anchored glycopolymers. Scale bars are 10 μm.
