The Xpress Dialyzers from scienova are ready-to-use dialysis systems for large quantities of small sample volumes. They allow fast, efficient desalting and purification of protein, RNA and DNA samples. The dialyzers have also been used for protein binding studies during drug development as well as clinical sample prep for testing of free hormones such as testosterone, cortisol, FT3 and FT4. The unique geometry of the dialysis cartridges reduces dialysis time and can be used with automated liquid handling systems. Xpress Dialyzers are available for a variety of sample volumes with several molecular weight cutoff (MWCO) choices.
The optional XDB Xpress Dialysis Box can replace the deep well plate for high sample purification in half the time with a large, shared buffer volume. With no buffer exchange, almost 99% removal of salts and small molecules can be reached with the XDB Box in some cases. The XDB Refill Kits allow simple replacement of all the dialyzer cartridges with the same design benefits as the standard Xpress dialyzer kits.
