I need the exact value of water and salt permeabilities of DOW RO membranes for my project.
Thank you.
For protein extraction i found a protocol that separate phosvitin from egg yolk using ultrafiltration trough 10 MWCO then uses the filtrate. But phosvitin molecular weight is 35 KDa. So how it is...
