Hi all,
We are about to concentrate purified antibodies and want to give
ultrafiltration a try. Starting material will be some 3-4ml containing
approximately 200ug of purified antibody. As we need the antibody as
concentrated as possible, we´d like to use a 100kDa MCO filtration unit
to reduce the volume to 25 to 50ul. As there are quite some brands on
the market, which ones do you out there use successfully?
