Characterization of the liposomes by DLS and cryoTEM. (a) Representative DLS size distributions of L, IgG L (Ab:SATA = 1:80) and aICAM-1 L (Ab:SATA = 1:80) that were prepared from a single batch of liposomes. The three types of liposomes display a similar narrow size distribution. CryoTEM was used to study the morphology of (b) L, (c) IgG L (Ab:SATA = 1:80) and (d) aICAM-1 L (Ab:SATA = 1:80). Lipid suspensions were mainly composed of single unilamellar liposomes. Scale bar = 500 nm.
