Profile: Creative Biogene specializes in developing and manufacturing recombinant adenoviruses, adeno-associated virus (AAV), and lentivirus for gene delivery & gene knock down. RNA interference (RNAi) is a phenomenon in which expression of an individual gene can be specifically silenced by introducing a double-stranded RNA (dsRNA), that is homologous to the gene, into cells. RNA molecules can specifically recognize other RNAs by sequence, structure, or a combination of both.
