Physical titer
WebbAbstract Accurate measurements of the physical and infectious titers of adenoviral vectors are crucial for evaluating preclinical studies and for the safety and efficacy of clinical studies. Unfortunately, there are no standardized methods of measurement, consequently variable and unreliable values are the result. Webbtested for transducing titer, infectious titer and physical titer using the protocols posted on the Reference Standards section of the Bioprocessing Journal web site. Results are …
