ABSTRACT:
Test carrier for the analytical determination of a constituent of a sample fluid by a specific binding reaction between two binding partners having biological affinity. A plurality of test layers is so disposed that they are wetted successively by the fluid and form a fluid transport path, in which one of the test layers is a fixing layer (18) which is a porous carrier matrix. The first of the two binding partners is fixed to the latter. The fluid containing the second binding partner flows through the fixing layer (18), at right angles to its surface, on the test carrier (10).
A largely complete binding reaction in an extraordinarily short time is achieved during the flow through the preferably very thin fixing layer (18) by the fact that a microporous plastics layer with a pore size P of at least 0.01 pm is used as the carrier matrix, and at the same time the size D of the second binding partner and the pore size P of the plastics layer are adjusted to one another so that the pore size P is at least twice and at most ten times as great as the size D of the second binding partner.
