RESUMEN
The purpose of the described method is the detection of and differentiation between RNA and DNA of human immunodeficiency virus (HIV)-derived lentiviral vectors (LV) in cell culture supernatants and swab samples. For the analytical surveillance of genetic engineering, operations methods for the detection of the HIV-1-based LV generations are required. Furthermore, for research issues, it is important to prove the absence of LV particles for downgrading experimental settings in terms of the biosafety level. Here, a quantitative polymerase chain reaction method targeting the long terminal repeat U5 subunit and the start sequence of the packaging signal ψ is described. Numerous controls are included in order to monitor the technical procedure.

The production and application of viral vectors are frequently performed genetic engineering operations. HIV-1-based lentiviral vectors, AAV2-based, and adenoviral vectors are amongst the most abundant viral vectors utilized for gene delivery. They are generally classified into risk group 1 or 2 (according to EU directive 2000/54/EC on the protection of workers from risks related to exposure to biological agents at work).
