Abstract: An apparatus for performing nucleic acid amplification reactions includes a thermally-conductive receptacle holder that includes multiple receptacle wells. Each well can receive a receptacle and has a through-hole extending from an inner surface of the well to an outer surface of the holder. The apparatus includes multiple optical fibers, and each optical fiber has a first end in optical communication with an associated well and a second end in optical communication with an excitation signal source and/or an emission signal detector. The first end of each optical fiber is moveable with respect to the through-hole. A cover is movable between an open position and a closed position relative to the receptacle holder, and the first end of each optical fiber moves with respect to the through-hole of the associated well as the cover moves to the open or closed position or when the cover moves into or out of contact with any receptacles within the wells.

Each receptacle well has an inner surface defined to receive a receptacle, and each receptacle well has a through-hole extending between the inner and outer surfaces thereof. The apparatus further includes one or more thermal elements for altering a temperature(s) of the receptacle holder, where the one or more thermal element are in contact with a side surface of the receptacle holder. There are two or more thermistors disposed in contact with the receptacle holder and a channel disposed within the side surface and containing wires and/or electrical connections for the two or more thermistors.

Abstract: Multiple receptacles containing a reaction mixture are transported to corresponding receptacle wells of a thermally-conductive receptacle holder in thermal communication with a support that is in thermal communication with a heat sink. The heat sink is pre-heated to a temperature above ambient temperature, and the temperature of the receptacle holder is cycled. Optical communication is established between each of the receptacle wells and an excitation signal source and an emission signal detector during cycling, and whether an emission signal is emitted from any of the receptacles is determined as an indication of the presence of a target nucleic acid.

Abstract: A first time/temperature data set includes temperatures and time stamps recorded at time intervals during a first thermal cycling process and a time stamp for each time interval, and a second time/temperature data set includes temperatures and time stamps recorded at time intervals during a second thermal cycling process. Signal emissions at different signal detecting positions are sequentially measured at different time intervals to generate first and second time/signal emission data sets for receptacles subject to the first and second thermal cycling processes, respectively. Signal emissions of receptacles subject to the first thermal cycling process are synchronized with specific temperatures of the first thermal cycling process by comparing time stamps of the first time/signal emission data set for each receptacle with the time stamps of the first time/temperature data set that correspond with the specific temperature.

Abstract: A method for performing a nucleic acid amplification assay employs a thermally-conductive receptacle holder with one or more receptacle wells, each conforming to an outer surface of a lower portion of a vial. A through-hole extends from an inner surface of each well to an outer surface of the holder. A thermal element is positioned proximal to the holder for altering a temperature of the holder. A signal detection module is configured to generate an excitation signal directed through the through-hole of the well and detect an optical emission from a fluid contained in the vial supported by the well. At least one well supports a capped vial containing a reagent for a nucleic acid amplification assay and including an opaque cap sealing an open end of the vial. The lower portion of the vial is contained within a well, and the cap is situated above a top surface of the holder.

The thermoelectric device may be situated between an upright portion of the support and the first side of the holder. A second force may be applied onto a top end of each receptacle in the holder by a cover moveable with respect to the receptacles between an open position and a closed position.
