  • 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.

  • Publication number: 20070275006
    Abstract: The present invention relates to an adjuvants, particularly to the use of a well-characterized plant based iridoid glycoside adjuvant from plant Picrorhiza kurroa, acting as an adjuvant against T-dependent antigen and specifically against HBsAg and typhoid antigens. The present invention also relates to the method of producing the iridoid glycoside adjuvant and the products utilizing such adjuvants for induction of cellular immunity. The adjuvants may be used alone or with specific antigens. The two antigens used in the study represents HBsAg, a recombinant antigen expressed in Pichia pastoris, and typhoid Vi polysaccharide purified from Salmonella typhi broth.

  • Publication number: 20070154880
    Abstract: A novel process for the purification of recombinant protein expressed as particle is herewith described. In this purification process, the protein is purified by hydrophobic interaction. The interaction of this protein step resulted in an increase in recovery and purity from 15%-80%. the protein further purified has its application in vaccines and pharmaceuticals.

  • Patent number: 7105327
    Abstract: The present invention is based on the isolation of a gene coding for streptokinase from Streptococcus equisimilis (ATCC 9542), its cloning, and expression in E. coli. Two different strategies were carried out for the production of enzymatically-active streptokinase. In the first strategy, streptokinase was expressed as an inclusion body without its signal sequence followed by purification, solubulization, and renaturation to obtain an active preparation. The purified enzyme was formulated and lyophilized. In the second strategy, enzymatically-active streptokinase is secreted into the culture medium. The enzyme was purified, formulated and lyophilized.
