20110117546	INCREASE OF SIGNAL SENSITIVITY USING DUAL PROBES IN PCR REACTIONS - A method increases the signal strength generated when performing real-time PCR on a target nucleic acid sequence. The method performs real-time PCR using forward primers, forward probes, reverse primers, reverse probes, nucleotides for strand/antistrand extension, and nucleic acid polymerase. Two different types of probes are used, a forward probe configured to anneal to a sense strand of a target nucleic acid sequence and a reverse probe configured to anneal to an antisense strand of the target nucleic acid sequence. The forward probe is complementary to an inner sequence of the target sense strand, and the reverse probe is complementary to an inner sequence of the target antisense strand. The forward probe and the reverse probe each include the same detectable element, that when released from the probe during strand extension results in an additive detectable signal.	05-19-2011
20110091873	INTEGRATED SAMPLE PREPARATION AND AMPLIFICATION FOR NUCLEIC ACID DETECTION FROM BIOLOGICAL SAMPLES - Beads are used to perform both a sample preparation and amplification process within a single processing chamber. A fluid sample including a plurality of cells is introduced into a processing chamber already including a plurality of beads. The plurality of cells are lysed within the processing chamber, and nucleic acid released from the lysed cells binds to the beads. The beads are retained in the processing chamber while the lysing reagents are removed. Amplification reagents, such as PCR reagents are added to the processing chamber and an amplification process is performed on the contents of the processing chamber. Nucleic acid captured on the beads is not eluted for amplification, instead amplification of the captured nucleic acid is performed while the nucleic acid is still bound to the beads. During the amplification process, the nucleic acid bound to the beads is amplified. Real-time or end-point detection can be performed on the content of the processing chamber to detect the presence of amplified product.	04-21-2011
