What is the genetic difference between retroviral and lentiviral vectors?

Honestly, that's a little too broad of a question to answer. Our suggestion is to look in the literature. Below is a webpage address that comes directly out of "Retroviruses" , which is the main reference for anything concerning retroviruses and retroviral vectors. http: //www. ncbi. nlm. nih. gov/books/bv. fcgi?rid=rv. section. 4357 Also the below reference is a good review on lentiviral vectors and its vectorology: Debyser, Current Gene Therapy, 2003, 3, 517-525, Biosafety of Lentiviral Vectors
