Stabilisation method for viruses or bacteria

The present invention relates to a method for stabilising viruses or bacteria, the method comprising embedding the viruses or bacteria in an aqueous solution, wherein the solution comprises: (i) at least three different amino acids; or (ii) at least one dipeptide or tripeptide and wherein the solution is free or substantially free of sugar(s), silanes and protein(s).

Method of long-term preservation of chemical and biological species using sugar glasses

A method of preserving the one or more chemical and/or biological species in a polymer matrix comprising pullulan and trehalose is described. The method includes combining the one or more chemical and/or biological species, an aqueous pullulan and a trehalose solution and drying the resultant mixture to provide a solid polymeric matrix. A polymeric matrix comprising one or more chemical and/or biological species and its use, for example, on surfaces for food preparation, for food preservation and in biological preparations is also described.

20200071679 · 2020-03-05 ·

The invention relates to the field of virology and tumor therapy. In particular, the present invention provides a recombinant herpes simplex virus (HSV) capable of specifically replicating at a high level in a tumor cell and effectively killing the tumor cell, but replicating at low levels in normal cells, thereby the recombinant herpes simplex virus of the present invention not only has high lethality against tumor cells, but also has significantly decreased side effects (especially neurotoxicity). Further, the present invention relates to a viral vector constructed based on the recombinant herpes simplex virus, a pharmaceutical composition comprising the recombinant herpes simplex virus or the viral vector, and the use of the recombinant herpes simplex virus or the viral vector. The recombinant herpes simplex virus of the present invention can be used to infect and kill tumor cells, and can be used for gene drug delivery into tumor cells for gene therapy.
