iBio develops and offers product

applications of its iBioLaunch and iBioModulator platforms, providing collaborators full support for turn-key implementation

of its technology for both proprietary and biosimilar products. The iBioLaunch platform is a proprietary, transformative technology

for development and production of biologics using transient gene expression in unmodified green plants. Advantages over other systems

include: success with proteins difficult or impossible to produce with other methods; broadly applicable to biologics, including

monoclonal antibodies, other therapeutic proteins and vaccines; enables rapid development and validation of modular, scalable,

and optionally robotic, multi-product manufacturing facilities; production time measured in weeks instead of months or more. Additional

benefits include a practically unlimited surge capacity for remedial action against bioterrorism and pandemic disease; product

entry that is unconstrained by traditional process patents, and significantly lower capital and operating costs for comparable

production. The iBioModulator platform is complementary to the iBioLaunch platform and enables significantly improved vaccine products

with higher potency and greater duration of effect. The iBioModulator platform can be used with any recombinant expression technology

for vaccine development and production. Further information is available at: www.ibioinc.com.
