The real-time polymerase chain reaction (PCR) uses fluorescent reporter molecules to monitor the production of amplification products during each cycle of the PCR reaction. This combines the DNA amplification and detection steps into one homogeneous assay and obviates the need for gel electrophoresis to detect amplification products. Appropriate data analysis and/or use of apposite chemistries also eliminates the need for Southern blotting or DNA sequencing for amplicon identification. Its simplicity, specificity, and sensitivity, together with its potential for high throughput and the ongoing introduction of new chemistries, more reliable instrumentation, and improved protocols, has made realtime PCR the benchmark technology for the detection of DNA.

linear to sample concentration over a very broad range, this linear correlation between PCR product and fluorescence intensity can be used to calculate the amount of template present at the beginning of the reaction.

There has been an explosion of protocols, instruments, and chemistries, which on the one hand is evidence for the popularity and ubiquity of the assay, but also highlights the need to be aware of problems associated with the use of nonstandardized assays for diagnostic assays.[1]

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
