A pseudovirus is a laboratory-created viral particle that mimics the structure of a real virus but lacks the ability to replicate and cause infection. Pseudoviruses are formed by encapsulating specific nucleic acid fragments within a viral capsid protein. Currently, the pseudoviruses launched by Hanbio Biotechnology are mainly lentivirus, adenovirus and adeno-associated virus.

Pseudoviruses are mainly used as positive control standard and internal control standard in viral nucleic acid test kits.
