| 摘要 |
The present invention relates to devices for carrying out quick immunochemical tests and to methods for the immunochemical determination of suitable proteins using this device. The device consists of a layer which has capillary activity and consists of a dry, porous, non-swelling, particulate material with molecular sieve properties, the pore size of the molecular sieve allowing penetration of the soluble antibodies used for the immunochemical detection of the antigens but allowing little or no penetration of the soluble immune complexes formed from antigen and antibodies. The layers with capillary activity are preferably contained in a glass or plastic capillary column or are attached to an inert support material. In the method according to the invention, a substrate sample is loaded onto one end of the device, and the immune complex which is formed where appropriate is separated from the antibodies by chromatography using a solvent and is detected. |
