Various types of viral vectors are being employed extensively as gene therapeutics to treat cancer and genetic diseases. Among the viruses that have been produced for human clinical trials (i.e. retrovirus, adenovirus, poxvirus, adeno-associated virus, and herpesvirus vectors) adenoviruses exhibit the lowest pathogenicity yet still infect an extensive range of cell types with high efficiency. These key characteristics make recombinant adenoviruses efficient gene-delivery vehicles and excellent research tools. However, the time-consuming and complex processes of generation, amplification, purification, and quality testing associated with production of recombinant adenoviruses make it difficult for many researchers to utilize these vectors. This is particularly true with respect to cell culture optimization and the virus propagation protocols employed in vector production. In this regard, the development of innovative cell culture techniques has become vital for optimizing vector production for gene therapy…

With the advent of whole cell-based therapeutics has come a growing standardized quality control and quality assurance of the processes employed for developing and manufacturing cellular materials, similar to the controls over traditional drugs and biologicals. Cellular therapeutics present unique process and quality control challenges due to the innate complexities of living cells, making it important to use whole cell assays to provide detailed pictures of the status and consistency of cell preparations that will be used to treat patients. This article illustrates how a cellular assay from Guava Technologies addresses these issues…
