PCR Basics
Polymerase chain reaction (PCR) is a method to amplify a target sequence from background nucleic acid . A way to make lots of copies of DNA
• Target DNA (example: environmental DNA) • 2 primers (20-30 nts long)• dNTP’s• Thermostable DNA polymerase• Mg2+ (cofactor for DNA polymerase)

What is PCR?
PCR Basic Steps
Quantitative Real Time PCR
Definition: Assay that monitors the accumulation of a DNA product from a PCR reaction in real time>> Fluorescence-based detection of amplification products through the use of a DNA-binding dye or hybridization probe>> PCR Real-time qPCR is used to quantify input nucleic acid by measuring the number of cycles required to reach a set level of product.>> Benefits over traditional PCR assaysl Sensitivity (as little a single copy)l Enhanced dynamic range of detection (7-8 magnitudes)l Increased reproducibilityl Increased throughputl Cost efficiency
l A linear increase follows exponential phase
l Eventually plateaus

Limitations of standard PCR
Amplification is exponential, but the exponential increase is limited:
In theory, the amount of DNA produced at every cycle should double,
Product(T) = (Template0) x 2n (n = # of cycles)
Standard PCR is as endpoint
96 identical reactions will have very different final amounts of fluorescence at endpoint
Real-Time PCR
Through the use of fluorescent molecules, real-time PCR has the ability to directly measure the reaction while amplification is taking place.
How is quantitative data collected?

Threshold Cycle, CT
l The point at which the fluorescence rises appreciably above backgroundl Threshold can be placed anywhere in the exponential (log-linear) phase
Threshold Cycle, CT
Threshold Setting
After baseline subtraction, a threshold line is set empirically or by a statistical calculation at a fluorescence value above background.
Threshold
Log View
• 1 CT Difference = 2 fold difference in starting template amount
• 3.3 CT Difference = 10 fold difference in starting template amount
ProductT=(Template0)2n
Where n=Number of Cycles
Mathematical Implications
Ideal PCR
Correlates strongly with the starting copy number
Threshold Cycle, CT
2n = 10 fold
n ln 2 = ln 10
n = ln10ln 2
n = 3.32
From CT values, we can determine the initial copy number

l DNA binding dyes are inexpensive compared to hybridization probes.
l EtBr is 25 times more fluorescent when bound to dsDNA
l SYBR Green I is 125 times more fluorescent brightly bound to dsDNA
