Centrifugal filter units are among the most reliable and efficient available, with a membrane ideally suited to concentrate peptides with molecular weights as low as 3kDa
Many 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 among the most reliable and efficient devices for the concentration of low weight peptides, says the company.
The 3kDa MWCO membrane incorporated into the Vivaspin 500 centrifugal filter unit is ideally suited to concentrate peptides with molecular weights as low as 3kDa, showing a 90% recovery.
Such outstanding results are said to be 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 three to six times faster than 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 described as the broadest in the industry, allowing a tailored solution to any concentration and desalting applications.
With a new 2kDa MWCO membrane also on its way from Vivascience, the company says these market innovators continue to lead the way in laboratory ultrafiltraion.
