What are the retention properties of Product D7884, Dialysis tubing benzoylated?
Benzoylation reduces the size of the pores in the membrane such that the molecular weight cut-off is reduced to approximately 2 kDa. Compounds with a molecular weight of 1200 will freely pass through the membrane. Compounds with a molecular weight of 2000 or greater will be retained by the membrane.
