Viral Stock Buffer Exchange Kit
Viral Stock Buffer Exchange Kit is supplied separately from the recombinant viral purification kits. All recombinant viral purification kits do not contain the viral stock buffer exchange kit.
The eluted recombinant virus 
is in a salt buffer but can be used directly for in vitro target cell transduction if the viral dilution is over 5X (i.e. 1.0μl of viral stock to 4μl culture medium). For higher titers of viral stock or viral dilutions less than 5X during transduction, a buffer exchange is required to make the viral stock suitable for such applications. This can be easily performed using our viral buffer exchange kit. The exchange filter included in the kit is applicable for all recombinant virus, but the exchange buffer differs.
