| 摘要 |
The invention relates to a device (12; 72) and method for optically measuring fluorescence of nucleic acids in test samples (14). The device (12; 72) comprises a plurality of sample wells (32) each for receiving an upright sample tube (16) made of a transparent material, having a side wall (20) and a bottom end (22) and containing one of the test samples (14) together with at least one fluorescent dye, at least one excitation light source (24; 74, 76, 78, 80) disposed in the vicinity of each sample well (32) for directing an excitation light beam through the side wall (20) of the sample tube (16) into the test sample (14) for exciting the dye, and an optical fluorescence detector (28) disposed underneath the bottom end (22) of each sample tube (16) for capturing fluorescence emitted from the dye in the test sample (14) upon excitation. |
