Lentiviral vectors are made by inserting genetic material into a lentivirus, which is a type of retrovirus. The genetic material is then packaged into a viral particle and used to deliver genes to target cells. Lentiviral vectors are used in gene therapy to insert a functional gene into cells, which can be used to treat genetic diseases. Lentiviral vectors can also be used to deliver genes to cells for research purposes. GMP (Good Manufacturing Practice) Lentiviral Vectors are lentiviral vectors that have been produced in a controlled environment according to GMP standards.
