    摘要： A sample container for minimizing evaporation of a contained volume of sample includes a container housing, a repuncturable self-sealing membrane, and a collapsible sample bag. The container housing includes an open end and a hollow interior region. The repuncturable self-sealing membrane configured to self-seal after repeated punctures is engaged in the open end of the container housing and includes an exterior surface exposed to the external environment and an interior surface oriented toward the hollow interior region of the container housing. The collapsible sample bag includes a proximate end that is permanently attached to the interior surface of the repuncturable self-sealing membrane.

    摘要： A system is provided for carrying out real time fluorescence-based measurements of nucleic acid amplification products. In a preferred embodiment of the invention, an excitation beam is focused into a reaction mixture through a surface, the reaction mixture containing (i) a first fluorescent indicator capable of generating a first fluorescent signal whose intensity is proportional to the amount of an amplification product in the volume of the reaction mixture illuminated by the excitation beam and (ii) a second fluorescent indicator homogeneously distributed throughout the reaction mixture capable of generating a second fluorescent signal proportional to the volume of reaction mixture illuminated by the excitation beam. Preferably, the excitation beam is focused into the reaction mixture by a lens through a portion of a wall of a closed reaction chamber containing the reaction mixture. The same lens is used to collect the first and second fluorescent signals generated by the first and second fluorescent indicators, respectively, in response to the excitation beam. The ratio of the fluorescent intensities of the first and second fluorescent signals provides a stable quantitative indicator of the amount of amplification product synthesized in the course of the amplification reaction.

    摘要： A pipette-loaded bioassay includes a measurement probe and a pipette tip. The measurement probe includes a probe head configured to launch an incident test signal and a connecting end configured to receive the incident test signal from a signal source. The pipette tip includes a sample interrogation region which is electromagnetically coupled to the probe head, the sample interrogation region configured to retain a plug of sample solution and constructed from a material which is substantially transparent to the incident test signal. The incident test signal electromagnetically couples through the sample interrogation region and to the molecular or cellular events occurring within the sample solution. The interaction of the incident test signal with the molecular or cellular events produces a modulated test signal which can be recovered and used to identify the molecular or cellular events occurring in a subsequently tested sample.
