Residual DNA analysis in influenza vaccine processing
To reliably measure residual DNA in both process samples and final vaccine by quantitative PCR (qPCR), DNA preparation prior to analysis is a necessity. Samples from the vaccine purification process c…

New Therapies Present Scaling Challenges
One major challenge to a scale-up strategy lies in the crucial step of transient transfection, which is when DNA is introduced into the mammalian cell. The genetic material to be introduced into the m…
