Transmission electron microscopy (TEM) images of spray-freeze dried (SFD) VLPs and non-spray-freeze dried VLPs. Mixed MS2-L2 VLPs and MS2 control VLPs were SFD with/without mucosal adjuvants (CT and MPLA) and the dry powders were reconstituted in PBS and analyzed (in comparison with fresh liquid VLPs) using a TEM. A) TEM of spray-freeze dried VLPs with CT/MPLA, B) TEM of spray-freeze dried VLPs without CT/MPLA, and C) TEM of fresh liquid VLPs. Images were taken under 30,000X magnification.
