Retroviral integration into host cell chromosomes was once thought to be random, but new evidence suggests that human immunodeficiency virus preferentially enters the neighborhood of activated genes.

Cis-elements within retroviral expression constructs increase vector titer and/or gene transfer efficiency. Several approaches for expressing multiple genes in a single vector are available. The ...

Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want to add and subtract two dimensional ...
