Viral transduction is the process of introducing foreign genetic material into a cell with a virus or viral vector. This method is a common tool used by researchers to enable stable introduction of a gene into the genome of a target cell or cells. Small molecules can be used to enhance the viral transduction process and increase target gene expression.

Viral transduction is a common process used by researchers for a range of processes, including but not limited to transgene expression, gene silencing, site-directed gene editing, generation of transgenic animals, expression of fluorescent proteins for imaging, induction of pluripotent stem cells, and stem cell reprogramming and differentiation.
Viral vectors, or viral particles, used to deliver genetic material into a cell are first made in a packaging cell line, commonly HEK293 cells. A plasmid containing the genetic material to be transferred is inserted into the packaging cell line, along with plasmids that code viral genes for reverse transcriptase, integrase and the viral capsid. The packaging cell line produces viral vectors that replicate within cells, which are then harvested and used to transduce target cells.
There are three main types of virus used for viral transduction; retroviruses, lentiviruses and adeno-associated viruses. Retroviruses are stable and replication-defective, meaning they don't contain sequences required by the virus to make proteins for viral replication and infection. However, they can only transfect cells that are actively dividing and so are unsuitable for use with cells that are post-mitotic, such as neurons. Lentiviruses are a subtype of retroviruses that can transfect non-dividing cells. Genetic material transfected in lentiviruses is integrated into the host cell genome and the viral vector remains in the cell, being passed to its progeny when the cell divides. Adeno-associated viruses also incorporate into the host cell genome and can infect both dividing and non-dividing cells.
Small molecules can be used to enhance viral transduction. For example, prostaglandin E2 (Cat. No. 2296) improves lentiviral transduction and increases viral vector copy numbers resulting in increased transgene expression in CD34+ hematopoietic stem and progenitor cells.
