摘要:
This invention relates to preparations of viruses, e.g. for vaccine or other pharmaceutical or research use, to their stabilization, and to processes of producing such preparations, as well as to their use, e.g. as vaccines or as virus vectors. The formulations comprise a sugar, a preservative, a dispersing agent, a thermal stability agent, a buffer, and up to three distinct types of amino acids without impacting the structural appearance of the lyophilized product.
摘要:
Methods and systems for determining the concentration of compounds, such as proteins, in compositions comprising adjuvanted complexes of the compounds are provided. The methods and systems generally comprise (i) measuring the intrinsic fluorescence of a composition comprising adjuvanted complexes of the compound and (ii) comparing the measured fluorescence intensity value to a calibration curve prepared using known concentrations of the compound. Also provided are methods and systems for determining percent adsorption of a selected compound to an adjuvant.
摘要:
The present disclosure relates to liquid and dried compositions comprising a live, attenuated or genetically modified herpesvirus and methods of preparing such compositions, in one aspect, the composition comprises at ieast two or more pharmaceutically acceptable exctpients, at ieast one of which is histidsne and at least one of which is a sugar or sugar alcohol. The composstions retain a sufficiently high infectious titre following storage or large-scale manufacturing steps, such as lyophilization.
摘要:

摘要:
This disclosure relates to modified Streptococcus pneumonia pneumolysm (PLY) proteins which lack hemolytic activity and can be used as immunogens in an immunogenic composition or vaccine against invasive pneumococcol diseases caused by S. pneumonia The modified pneumolysm proteins comprise ammo acid substitutions at threonine 65, glycine 293 and cysteine 428 Nucleic acids, polypeptides encoded thereby, compositions containing the same, methods for using such nucleic acids, polypeptides and compositions are also provided
摘要:
Provided herein are compositions and methods for eliciting an immune response against Streptococcus pneumoniae. More particularly, the compositions and methods relate to immunogenic polypeptides, including fragments of PhtD and variants thereof, and nucleic acids, vectors and transfected cells that encode or express the polypeptides. Methods of making and using the immunogenic polypeptides are also described.
摘要:
Vaccines against Chlamydia are formulated based on the peptidoglycan-associated lipoprotein (PaL) . The vaccines contain PaL sequences from various Chlamydia strains, the sequences sharing immunologically significant epitopes.
摘要:
This disclosure relates to a method of preventing or treating a recurrence of acute otitis media in a subject at risk comprising administering a therapeutically effective amount of a composition, at least once to the subject. The composition administered comprises at least one immunogenic polypeptide selected from the group consisting of Streptococcus pneumoniae PhtD, PhtE, PcpA, LytB and detoxified pneumolysis
