Ultrafiltration cutt-off 200kDa
« on: December 10, 2009, 08:50:25 AM »
Hello,
does somebody know where to buy ultrafiltration membrane discs with molecular weight cutoff 200kDa? I searched the internet without any success :(. Or if somebody has a different idea how to separate protein solution with different molecular weights? I need the smaller fraction (0-200kDa), but I need to avoid any dilution (GPC is not suitable). Thanks. Tom

Have you tried Spectrapor? They specialize on these products.
You could also try Sigma, as they usually sell products from other brands.
