SubscribeMany laboratory applications now require fast and accurate recovery and concentration of peptides, such as in protein proteolysis and protein purification experiments. Vivaspin 500 centrifugal filter units from the Sartorius Vivascience range have proven to be amongst the most reliable and efficient method for the concentration of low weight peptides.
The 3 kDa MWCO membrane incorporated into the Vivaspin 500 centrifugal filter unit is ideally suited to concentrate peptides with molecular weights as low as 3 kDa showing a 90% recovery. Such outstanding results are due to the excellent design of these filtration units that optimise retentate recovery.
Vivaspin high-speed concentrators pioneered the use of vertical-mounted ultrafiltration membranes, a design which minimises fouling and significantly increases membrane area. They concentrate 3 to 6 times faster than the typically encountered ultrafiltration devices with horizontal membranes, without compromising recovery and the graduated concentrate window facilitates operation and sample recovery.
Moreover, the range of available membranes and centrifugal devices is the broadest in the industry, allowing a tailored solution to your concentration and desalting applications. With a new 2 kDa MWCO membrane also on its way from Vivascience, these market innovators continue to lead the way in laboratory ultrafiltraion.
