一般描述
Ultrafiltration membranes are typically made from regenerated cellulose or polyethersulfone (PES). The material of choice will greatly depend on sample compatibility. The choice of membrane nominal molecular weight cut-off (NMWCO) will depend on the molecular weight (MW) of the macrosolute that is to be retained. Membrane choice will have a significant impact on performance. As a rule, the NMWCO should be 2-3 times smaller than the molecular weight of the solute to be retained when using regenerated cellulose and 4-5 times smaller for Biomax® PES membranes.,Diafiltration uses ultrafiltration membranes, either in centrifugal or pressure-driven devices such as the Amicon® Stirred Cell for efficient buffer exchange. Unlike dialysis tubing, ultrafiltration membranes can be used for both sample concentration and buffer exchange, thus minimizing sample transfers and reducing sample loss.
应用
