Case Study: Oncolytic Adenovirus Production
Selectively engineered, the virus not only destructs the target tumor cell, but also stimulates the host’s anti-tumor immune response.
This case study describes a robust upstream process and downs…

Moving PAT from Concept to Reality
Numerous at-line analyses evaluate host cell proteins (HCPs), DNA, viable cell density, bioburden, aggregates, product concentration, and particulates.
One of the greatest difficulties with many c…

Emerging Therapies Test Existing Bioanalytical Methods
Most of the vectors utilized are likely to have modifications that will trigger the host to recognize it as “foreign” and elicit an immune response that may change the clearance of the vector prior to…
