WebNov 14, 2003 · Residual infectivity of the treated viruses and bacteria was determined. Results The prerequisites for producing CAP films which are soft, flexible and dispersible in water, resulting in smooth gels, are combining CAP with HPC (other cellulose derivatives are unsuitable), and casting from organic solvent mixtures containing ≈50 to ≈65% ethanol … WebInfectious titering is used to determine the infectivity of viral vectors. To perform infectious titer assays, dilutions of the viral vector are “sprinkled” on cells in culture, and the infectious virus can be detected using qPCR as an endpoint readout. qPCR serves as a surrogate for manual observation of cytotoxic effects, such as counting the number of dead …
