Impurity clearance
Witrynapurity and a large (retained) product on impurity clearance. Experiments were performed using D-tryptophan and bo-vine serum albumin as a model system. The results clearly demonstrate that binding interactions can dramatically reduce the rate of small impurity removal, leading to large WitrynaAbstract. As the field of plasmid DNA-based vaccines and therapeutics matures, improved methods for impurity clearance monitoring are increasingly valuable for process development and scale-up. Residual host-cell RNA is a major impurity in current large-scale separation processes for the production of clinical-grade plasmid DNA.
