Abstract
The present disclosure relates to compositions, methods, mixtures, and kits for detecting the presence of, and for removing, a virus from a product produced in an insect cell. The disclosure also relates to proteins, peptides, polypeptides, drug substances, biological products, vaccine antigens, and virus-like particles that are produced in an insect cell and that are free or substantially free of a virus. The disclosure also relates to compositions, methods, assays, and kits for detecting a rhabdovirus in a sample.

1-30. (canceled)
A composition derived from an Sf9 or Sf21 cell, or a cell passaged therefrom, wherein the composition is substantially free of a viral genome comprising a nucleotide sequence having at least 70% homology to SEQ ID NO:1.
A method for detecting a virus comprising detecting a nucleic acid sequence comprising at least 50 contiguous nucleotides of SEQ ID NO:
- 1 or the reverse complement sequence of SEQ ID NO:
- 1.
A method of producing a biological product using a rhabdovirus-free Sf9 or Sf21 insect cell, or a rhabdovirus-free cell passaged therefrom, wherein the method comprises the steps of:
- a) providing the rhabdovirus-free Sf9 or Sf21 insect cell, or the rhabdovirus-free cell passaged therefrom;
- and
- b) producing the biological product in said rhabdovirus-free cell.
A rhabdovirus-free Sf9 or Sf21 insect cell, or a rhabdovirus-free cell passaged therefrom.
A kit for detecting a sequence with at least 70% homology to SEQ ID NO:
- 1.
A method for removing a virus from a composition, wherein the virus comprises a sequence having at least 70% homology to SEQ ID NO:
- 1.
