An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, performing an analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material, and a device for holding containers of reagents in a temperature controlled environment. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte.

摘要:
A computer-implemented method for determining the amount of an analyte of interest in a sample, the method comprising (a) forming amplification products from an analyte of interest, (b) collecting signal data with a signal measuring device concurrently with the formation of amplification products, the collected signal data comprising periodic measurements of the level of a signal emitted by the sample, wherein the level of signal emitted by the sample corresponds to the amount of amplification products formed by the sample, (c) storing the collected signal data in computer-readable media; and (d) using a computer programmed with an algorithm, which, when executed by the computer, is configured to cause the computer to access the data stored in step (c) and to adjust the data collected in step (b) to remove background contributions to the measured levels associated with sources other than the presence of the analyte of interest, normalize the data adjusted in step (d)(1) by dividing the adjusted data by the maximum level measured, adjusted to remove background contributions, approximate a curve through a portion of the adjusted, normalized data between a predetermined low bound stored on computer-readable media and a predetermined high bound stored on computer-readable media, determine an emergence time at which the curve approximated in step (d)(3) crosses a predetermined threshold data level and determine the amount of the analyte of interest by comparing the emergence time determined in step (d)(4) with threshold times determined for known amounts of the analyte of interest and stored on computer-readable media.

摘要:
A formulation for use in preventing nucleic acids from acting as templates in an amplification reaction when the solution is combined with a nucleic acid deactivating agent, the formulation comprising a corrosion-inhibiting agent, a wetting agent, and a solubilizing agent, wherein each of said agents remains substantially in solution at 22°C, and wherein each agent is present in an amount that when the formulation is combined with an amount of a deactivating agent sufficient for the combined formulation to substantially deactivate nucleic acids, the corrosion-inhibiting agent reduces the corrosive properties of the deactivating agent, the wetting agent improves the dispersion properties of the deactivating agent on a solid surface and/or increases the solubility of the deactivating agent and/or other material that may be present on a solid surface or in a formulation, and the solubilizing agent increases the solubility of at least one of the deactivating agent, the corrosion-inhibiting agent, and the wetting agent.
