    • The present invention provides methods for the purification of cell-associated viruses from adherent cells (e.g., MDCK or Vero cells). In particular, the present invention provides purification methods for the production of immunogenic compositions comprising a live attenuated cell-associated virus (e.g., an attenuated respiratory syncytial virus (RSV) or cold- adapted, and/or temperature sensitive influenza virus) that result in levels of host cell DNA (HCD), host cell protein (HCP) and non-specific endonuclease (e.g., Benzonase), which are below the specifications required by regulatory agencies. The immunogenic compositions can be used to actively immunize subjects or to generate antibodies for a variety of uses, including passive immunization and diagnostic immunoassays.
    • 本发明提供了用于从贴壁细胞(例如MDCK或Vero细胞)纯化细胞相关病毒的方法。 特别地,本发明提供用于产生免疫原性组合物的纯化方法,其包含活减毒细胞相关病毒(例如,减毒呼吸道合胞病毒(RSV)或冷适应性和/或温度敏感型流感病毒),其导致 宿主细胞DNA(HCD),宿主细胞蛋白(HCP)和非特异性内切核酸酶(例如Benzonase)的水平低于管理机构要求的规格。 免疫原性组合物可用于主动免疫受试者或产生用于多种用途的抗体,包括被动免疫和诊断性免疫测定。
