摘要:
The invention comprises a membrane and device and method for removing proteases from fluids, particularly from biological fluids and pharmaceutical solutions, which uses a microporous membrane body, whereby inhibitors that selectively bind proteases are coupled to the membrane body by chemically activated groups.

摘要:
The invention describes a membrane and a method of making and using the same, the membrane being made from a microporous membrane body with an affinity ligand capable of interacting with at least one type of biomolecule found in a fluid, whereby the membrane body may be stored in a dried state yet retain the activity of the affinity ligand.
摘要:
There is disclosed a membrane process for the purification of nucleic acids in aqueous solutions whereby a lasting reduction of endotoxin content is achieved. The process is suitable for small or large volumes and can be carried out quickly and with simple apparatus.
摘要:
A dead-end filtration unit without a housing comprising at least one filter cassette, each cassette comprising a plurality of laminar sections of porous adsorptive membrane, which have been rendered fluid-impermeable on their peripheries, the cassettes being sealingly compressed between two filter retainers fitted with feed inlet and permeate outlet and wherein the laminar sections are made of the same or different membrane adsorber types.
