Protein purification

Protein fractionation using ultrafiltration is feasible after extensive process optimization, yet the poor selectivity of membranes is still one of the critical factors limiting the application of membrane systems to protein fractionation. Our present work on protein fractionation uses sandwich ultr

High-performance tangential flow filtration (HPTFF) is a new technology for protein and nucleotide purification. Conventional ultrafiltration (UF) is limited to separation of solutes that differ by tenfold in size. HPTFF is a twodimensional purification method that exploits differences in both size
