Abstract: Methods and systems for processing signals to minimize the effects of dye crosstalk. Deconvolution of multiplexed dye signals can include corrections for residual error determined from experimental measurements. Residual error corrections can account for reaction or assay specific factors and modify the subsequent filtering of signals. Correction values can be determined for specific dye-probe conjugates to minimize dye crosstalk and may be combined with residual error correction to further minimize errors in spectral deconvolution. Apparatus, systems, and computer-readable media can process signals and modify filters based on values obtained using the methods.

Abstract: Exemplary embodiments provide microfludic devices and methods for their use. The microfluidic device can include an array of M×N reaction sites formed by intersecting a first and second plurality of fluid channels of a flow layer. The flow layer can have a matrix design and/or a blind channel design to analyze a large number of samples under a limited number of conditions. The microfluidic device can also include a control layer including a valve system for regulating solution flow through fluid channels. In addition, by aligning the control layer with the fluid channels, the detection of the microfluidic devices, e.g., optical signal collection, can be improved by piping lights to/from the reaction sites. In an exemplary embodiment, guard channels can be included in the microfluidic device for thermal cycling and/or reducing evaporation from the reaction sites.

Abstract: Systems and methods for normalizing detected emission data collected in real-time polymerase chain reaction (RT-PCR) and other reactions, are provided. In some embodiments, a sample plate can be loaded with a fluorescent dye and subjected to a real-time PCR reaction. During the initial cycles, detected emissions that correspond to the background signal contributed by the plate, buffer, and other non-reactant pieces of the reaction system and chemistry can be identified. The raw emission data can be normalized by dividing the emission data by the identified baseline signal. According to various embodiments, the normalized amplification profile can normalize to an initial value of 1, because the actual signal emerges from the baseline at the point exponential growth begins. A normalized amplification profile based on a ratio to the baseline can create a more uniformly scaled amplification curve across different samples, filters, wells, dyes, or machines.

Abstract: Systems and methods are provided for calibrating emission data or other information signals collected during a polymerase chain reaction (PCR), amplification reaction, assay, process, or other reaction. Calibration of multiple detectable materials can be achieved during a single cycle or run, or during a plurality of runs of the reaction. A reading from every well, container, or other support region of a sample support does not have to be taken. Interpolation can be used to determine values for emission data or other information signals that were not taken, or are unknown, using detected emission data, or other detected information signals. By calibrating the detected emission data and the interpolated data, a more accurate reading of emission data or information signal can be obtained.
