Abstract:
Experimental studies on Zika virus (ZIKV) may require improvement of infectious titers in viral stocks obtained by cell culture amplification. The use of centrifugal filter devices to increase infectious titers of ZIKV from cell-culture supernatants is highlighted here. A mean gain of 2.33 ± 0.12 log10 DICT50/mL was easily and rapidly obtained with this process. This efficient method of ultrafiltration may be applied to other viruses and be useful in various experimental studies requiring high viral titers.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
