Lentivirus production refers to the process of generating lentiviral particles for research or therapeutic applications. This involves co-transfection of plasmids (packaging, envelope, and transfer plasmids) into a host cell line (usually HEK293T cells) to produce the viral particles. The process includes transfection, harvesting of viral supernatants, and purification to obtain high-titer, functional lentivirus. Lentivirus production is a critical step in applications such as stable gene expression, gene knockdown using shRNA, and preclinical gene therapy studies.

A lentivirus vector is a type of viral vector derived from lentiviruses, such as HIV-1, which is commonly used in molecular biology and gene therapy. Lentiviral vectors are highly versatile tools for delivering genetic material into dividing and non-dividing cells, making them ideal for long-term gene expression and stable transduction. These vectors can carry large genetic payloads and can be engineered with various promoters and regulatory elements to ensure precise gene delivery and expression in targeted cells.
