Abstract
PURPOSE: To prepare serum for cultivation exhibiting high propagating properties, filtering a growth inhibiting component and a component to induce cell degeneration in the serum using a separating membrane having a specific permeability to albumin and permeability to gamma-glubulin.
CONSTITUTION: By using a separating membrane made of a material having a permeability to albumin of ≥30%, preferably ≥40%, most preferably ≥50%, and a permeability to gamma-globulin of <10%, serum is filtered by a method wherein a line speed at the membrane face can be made high and the clogging by protein cake reduced.
