Fig 1 — Spherical (blue) and rod (red) shaped particles were adsorbed with ligand (A) BSA and rabbit anti-BSA IgG, or (B) OVA and rabbit anti-OVA IgG, and probed with the same fluorescein isothiocyante (FITC) labeled secondary anti- rabbit IgG to confirm ligand coating. Negative controls (black) were plain particles incubated with BSA (A) or plain particles (B) and FITC labeled secondary anti-rabbit IgG. Representative traces are shown, which were consistent across two independent batches of ligand coated particles.
