Appeal No. 98-2792 Application 08/516,257 As explained in the last paragraph on page 13 of the specification, the analog-analyte binds with a receptor to form an analog-analyte-receptor complex. When the analyte molecules are introduced into the processing chamber by diffusion through the semi-permeable membrane (8), they may then bind with a receptor to form an analyte-receptor complex. Apparently the receptor material has a higher affinity for the analyte molecule than for the analog-analyte molecule, because the formation of an analyte-receptor complex frees a previously bound analog- analyte molecule. The analog-analyte molecules are labeled by covalent coupling with an appropriate dye (specification, page 14) so that they fluoresce in response to excitation energy sent into the processing chamber (i.e., via the optical fiber (30)). The degree of interaction of the analyte with the receptor material in the processing chamber of the sensor is 4Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
