| 摘要 |
The invention provides a composition and a method for preserving a non-enveloped viral vector. The composition comprises (a) trehalose, (b) a divalent metal salt, a cationic polymer, or a combination thereof, (c) a multiplicity of non-enveloped viral vector particles, and (d) a liquid carrier. Non-enveloped virus particles are stable in the composition in a liquid form, at elevated temperatures, for a sustained period of time.
