20150031015 | IDENTIFICATION OF POLIOVIRUS STRAINS - The present invention relates to methods for identifying and/or distinguishing polioviral strains, in particular polioviral strains used in vaccine production. The methods are based on selective hybridisation with oligonucleotides, i.e. primers and/or probes, that allow to distinguish between closely related but different polioviral strains on the basis of nucleotidepolymorphisms existing between those polioviral strains. Preferably, the methods employ amplification or amplification-ligation assays for detecting the selective hybridisation. The invention further relates to oligonucleotides for use in the methods of the invention and kits comprising such oligonucleotides and optionally enzymes and buffers for carrying out the methods of the invention. | 01-29-2015 |
20150030629 | METHODS AND COMPOSITIONS FOR STABILIZING DRIED BIOLOGICAL MATERIALS - The present invention relates to methods for producing dried formulations of biopharmaceutical agents that aim to minimize the loss of activity of the agents upon drying and to provide dried formulations with an extended shelf life. The method comprises the step of drying an aqueous solution comprising, in addition to the biopharmaceutical agent, at least an amino acid, a polyol and a metal salt. Preferably the amino acid is glutamate, the polyol is sorbitol and optionally also mannitol and the metal salt is a magnesium salt. The solution is dried by vacuum drying or by lyophilization. The methods are particularly useful for preparing dried formulations of viruses such as poliovirus or respiratory syncytial virus to be used for vaccination. The invention also relates to dried formulations prepared in accordance with the methods of the invention and to their use as medicaments, e.g. as vaccines. | 01-29-2015 |
