Gene Regulation Tool

Viral vectors are essential tools in molecular biology, enabling efficient delivery of target genes into both cultured cells and entire living organisms. Their infection efficiency of these viral vectors typically surpasses that of plasmid transfection, especially for hard-to-transfect cell types such as primary cells and stem cells. This makes viral vectors crucial for overexpressing exogenous genes and conducting gene knockdown. Commonly used viral vectors include lentiviral vectors (LV), adenoviral vectors (AdV), and adeno-associated virus vectors (AAV).

MedChemExpress leverages established viral vector manufacturing techniques to offer a comprehensive range of lentiviral and adenoviral packaging services, suitable for manipulating both coding and non-coding genes. Our virus production process follow internationally recognized standards, ensuring delivered viral products meet titer specifications and are free from contamination, which guarantees suitability for a diverse range of experimental requirements.
