Abstract:
The present invention relates to a novel lipoprotein particle, methods for preparing and purifying the same, its use in medicine, particularly in the prevention of malarial infections, compositions/vaccines containing the particle or antibodies against the protein particle such as monoclonal or polyclonal antibodies and use of the same, particularly in therapy. In particular it relates to an immunogenic protein particle comprising the following monomers: a. a fusion protein comprising sequences derived from a CS protein of P. vivax and the S antigen of Hepatitis B (CSV-S), and b. a fusion protein comprising sequences derived from CS protein of P. falciparum and S antigen of Hepatitis B (RTS), and c. optionally the S antigen derived from Hepatitis B.
Abstract:
The invention relates to a cytomegalovirus (CMV) gB polypeptide comprising at least a portion of a gB protein extracellular domain comprising a fusion loop 1 (FL1) domain and a fusion loop 2 (FL2) domain, wherein at least one of the FL1 and FL2 domains comprises at least one amino acid deletion or substitution.
Abstract:
The present invention relates to a novel lipoprotein particle, methods for preparing and purifying the same, its use in medicine, particularly in the prevention of malarial infections, compositions/vaccines containing the particle or antibodies against the protein particle such as monoclonal or polyclonal antibodies and use of the same, particularly in therapy. Furthermore, particles with the specific ratio can be prepared by employing yeast, Saccharomyces cerevisiae or Pichia pastoris. In particular it relates to an immunogenic protein particle comprising the following monomers: a. a fusion protein comprising sequences derived from a CS protein of P. vivax and the S antigen of Hepatitis B (CSV-S), and b. S antigen derived from Hepatitis B virus, and characterised in that the ratio of S to CSV-S is in the range 0.1 to 1. Suitably, the ratio of S to CSV-S is in the range 0.19 to 0.30 or 0.68 to 0.80.

Abstract:
Hollow microspherical, mineral or hard plastic, fillers are used to increase the insulation properties of thermoplastic olefin compositions, especially where used in extruded profiles, sheets or tapes. The thermoplastic olefins comprise a thermoplastic phase and a rubber phase wherein the rubber is at least partially cross-linked by dynamic vulcanization. The microspherical fillers can be added by melt blending with the pre-formed thermoplastic olefins. The natural wear-resistance, oxidative stability and thermal insulating properties of thermoplastic olefins, with the enhancement from the hollow microspheres make them particularly suitable for marine conduits, such as those used in the off-shore drilling industry in flexible pipelines, electrical cables and tethering lines.
Abstract:
This invention relates to novel HIV polypeptide and polynucleotide fusions of Gag, Pol and Nef which are useful in immunogenic compositions and vaccines. The invention relates in particular to a polypeptide which comprises Nef or an immunogenic fragment thereof, and p17 Gag and/or p24 Gag or immunogenic fragments thereof, wherein when both p17 and p24 Gag are present there is at least one HIV antigen or immunogenic fragment between them. The polypeptide may also comprise Pol or RT or an immunogenic fragment thereof.
