Viral vectors have been widely used as gene delivery vehicles. Compared to the conventional transfection methods, transduction usually results in much higher gene delivery efficiency, sometimes almost 100%. These are especially useful for gene delivery into primary cells or stem cells which is recalcitrant to conventional transfection methodologies. However, construction of a viral vector is a laborious process, and most commercial services in this area have so far been either too expensive or not user-friendly. With years of experience, Creative Biogene has launched a powerful QVirusTM Platform for Lentivirus, Retrovirus, Adeno-associated Virus (AAV), Adenoviruses, Retrovirus, Oncolytic virus, etc.
