3 01 PCR vs Real-time PCR

4 What is DNA & What is PCR? NANOBIOSYS 4 DNA (deoxyribose nucleic acid) is the genetic material of most organisms. It consists of the building blocks adenine, guanine, cytosine, and thymine (abbreviated A,G,C,T), also called nucleotides, or more specifically deoxynucleotide triphosphates (dntps). In nature, DNA is a double helix consisting of two strands of varying nucleotide combinations. The nucleotides on the one strand complement the nucleotides on the matching strand by pairing A to T and G to C. This pairing or bonding, causes the two strands to twist around each other like a spiral staircase. Polymerase chain reaction (PCR) is a technique used to amplify DNA. This technique provides the most specific and sensitive assays available. From a single DNA molecule and specific building blocks, subsequent DNA copies can be made.

6 Principle of PCR Mimicking of Replication NANOBIOSYS 6 A single strand of DNA cannot be analyzed easily, but billions of copies of DNA can. In nature cells copy their DNA using replication. When any cell divides, enzymes called polymerases make a copy of all the DNA in each chromosome. To do this the two DNA chains of the double helix are unzipped. As the two strands separate, DNA polymerase makes a copy using each strand as a template. This process can be duplicated in the lab by mixing the DNA with nucleotides and other chemicals and repeatedly heating and cooling the DNA strand. Starting with one copy of DNA, two copies are made after one cycle, four after two cycles, etc. After 30 cycles, PCR will produce over a billion DNA copies that can then be measured.

7 How does PCR Work? NANOBIOSYS 7 What we need? Master Mix with; <Template Sample DNA/ Primers (and Probe)/ dntps/ Enzyme Polymerase/ Buffer/ Water> PCR Steps 1. Denaturation The first part of the process separates the two DNA chains in the double helix. This is done simply by heating the mixture to 90 95ºC (about 200ºF). 2. Annealing The primers cannot bind to the DNA strands at such a high temperature, so the mixture is cooled to 60ºC (about 140ºF). At this temperature, the primers bind or anneal to the ends of the DNA strands. 3. Extention The final step of the reaction is to make a complete copy of the templates. The enzyme begins adding nucleotides to the primer and eventually makes a complementary copy of the template.

8 What is Real-time PCR? NANOBIOSYS 8 With TaqMan Probe A hydrolysis probe (often sold under the tradename TaqMan ) provides a quantitative signal of amplified samples. The shortcoming of this technique is that the probe is destroyed during the PCR process. The probe consists of a DNA strand of approximately bases with a quencher dye at one end and a reporter (fluorescent) dye at the other end. After the probe hybridizes with the target DNA strand, light from the instrument s LED stimulates the reporter dye to emit a signal, which is absorbed by the quencher. When the enzyme hydrolyzes (decomposes with water) the probe, the quencher is separated from the reporter (along with the synthetic DNA bases), and the excited reporter fluoresces. A detectable signal occurs only when the probe is hydrolyzed by the enzyme. As DNA is amplified, this process repeats, increasing the fluorescent signal of the sample.
