  • Patent number: 8865184
    Abstract: The present invention relates to vaccine formulation capable of eliciting protective immune response against Chikungunya virus infection in humans and other mammalian hosts. The immunogenic formulation comprises purified inactivated Chikungunya virus in a stable formulation. Methods of propagation and purification of the virus are discussed. The inactivated virus formulation is non-infectious, immunogenic and elicits protective immune response in mammalian host. The immunogenic composition is formulated for in vivo administration to humans. The invention also discusses the strategy of developing a subunit vaccine using the recombinant viral proteins as antigens for immunization. The recombinant virus antigens that are potentially immunogenic can be used in diagnosing for the presence of the virus.

  • Patent number: 7625692
    Abstract: Systems and methods are described for improved yield and line width performance for liquid polymers and other materials. A method for minimizing precipitation of developing reactant by lowering a sudden change in pH includes: developing at least a portion of a polymer layer on a substrate with an initial charge of a developer fluid; then rinsing the polymer with an additional charge of the developer fluid so as to controllably minimize a subsequent sudden change in pH; and then rinsing the polymer with a charge of another fluid. An apparatus for minimizing fluid impingement force on a polymer layer to be developed on a substrate includes: a nozzle including: a developer manifold adapted to supply a developer fluid; a plurality of developer fluid conduits coupled to the developer manifold; a rinse manifold adapted to supply a rinse fluid; and a plurality of rinse fluid conduits coupled to the developer manifold.
