Method and device for determination of proteins employing antigen/antibody reactions

摘要

A body sample to be analyzed is passed through a series of laminated membranes which may be considered as two separate membrane units. The first unit comprises a separator membrane superimposed in capillary contact with a reactor membrane. The second unit comprises a collector membrane superimposed on a capture membrane or as an extension of the capture membrane. Initially the units are not in contact with each other, but at the appropriate time they are brought into contact. Selected antibodies are appropriately distributed throughout the membrane structure. In a preferred embodiment, the devices of the present invention are used for the separation of low density lipoproteins from whole blood.
