Custom Virus Packaging

Lentiviral and retroviral vectors are one of the most efficient methods of gene delivery to mammalian cells both in vitro and in vivo. Through years of experience with lentiviral and retroviral vectors, ALSTEM has developed its own proprietary virus packaging systems and efficient protocols for the rapid generation of pseudoviral particles. If you don't see what you're looking for below, please don't hesitate to Contact Us so we can provide you with your desired service.

ALSTEM offers express lentiviral and retroviral packaging services to produce high-quality, high-titer virus particles using your viral construct with a turnaround time of 2-3 weeks. Save yourself the time and effort of preparing your own virus, and receive ready-to-transduce viral particles.
