Polymerase Chain Reaction 특정 DNA 부위를 특이적으로 반복 합성하여 시험관내에서 원하는 DNA 분자 를 증폭시키는 방법으로서, 아주 적은 양의 DNA 를 이용하여 많은 양의 DNA 합성이 가능

Polymerase Chain Reaction The three steps of PCR Step 1. Denaturation : double strand DNA 를 열에 의해 single strand 로 분리. Step 2. Annealing : DNA primer 가 DNA 에 결합하는 단계. Step 3. Extension : DNA polymerase 에 의해 DNA 합성이 일어나는 단계.

Overlap-extension PCR Lee, J et al. BioTechniques 36, (2004) PCR-mediated INSERTION mutagenesisPCR-mediated DELETION mutagenesis OE-PCR 은 PCR 방법을 이용하여 단백질 분자 내의 특정 아미노산을 다른 아미노산으로 치환하 는 여러 방법 중 하나이다. 단백질 내의 특정 아미노산만을 다른 아미노산으로 변경하기 위해서 는 치환 아미노산에 해당되는 DNA 염기서열을 유전자상에서 쉽게 치환할 수 있도록 해야 한다. 치환하고자 하는 DNA 염기서열을 변형시키기 위해서 OE-PCR 에서는 4 개의 서로 다른 primer 들 을 사용하여 두 번의 연속적인 PCR 을 수행해야 한다.

Primer Primary PCR using chimeric primers –Primer A + Primer B (chimeric primer with primer C sequence) –Primer D + Primer C (chimeric primer with primer B sequence) –Primer B  COMPLEMENTARY SEQUENCE  Primer C PCR construct purification through gel elution –Intermediate PCR construct (A-B & C-D) Ligation PCR using outer primers (A and D) –Using Intermediate PCR construct (A-B + C-D) as a DNA template –Final product is mutagenized PCR construct which has deleted region

Primer design 시 주의사항 1) 길이는 20~30bp 로 제한한다. → 너무 짧으면 결합력이 약하고 너무 길면 시간과 효율면에서 좋지 않음 2) G+C% 가 50~60% 로 구성되어야 하며 purine 과 pyrimidine 염기의 연속적인 배열은 피해야 한다. 3) 한 쌍의 primer 가 부분적으로 서로 상보적이지 말아야 한다. → primer-primer dimer 의 형성 가능성을 배제하기 위함 Primer

Primer design 시 주의사항 4) Primer 의 3’ 말단에 G or C 가 3 개 이상 연속적으로 오지 않도록 한다. → 5’ 말단 sequence 는 annealing 에 크게 중요한 역할을 하지 않지만 3’ 말단 sequence 는 PCR product 가 extension 하는 부위이기 때문에 PCR 의 sensitivity 와 specificity 에 중요한 역할을 함. 3 개 이상의 G or C 는 비특이적인 증폭을 야기하므로 피하는 것이 좋음 5) Primer 의 3’ 말단에 T 가 오지 않도록 한다. → Thymine 은 올바르지 못한 다른 염기와 misparing 할 가능성이 높음 6) Tm 값이 동일한 두 primer 설계 ( 또는 차이가 5 ℃이하 까지 설계 ) - Tm value = [4*(G+C) + 2*(A+T)] * annealing temp. = Tm – 3 ℃ (or 5 ℃ ) Primer

Agarose gel electrophoresis of DNA

Gel extraction Gel Slice and PCR Product Preparation Dissolving the Gel Slice 1. Following electrophoresis, excise DNA band from gel and place gel slice in a 1.5ml microcentrifuge tube. 2. Add 10μl Membrane Binding Solution per 10mg of gel slice. Vortex and incubate at 50–65°C until gel slice is completely dissolved(10min). Binding of DNA 1. Attach Vacuum Adapter to manifold port and insert SV Minicolumn into Adapter. 2. Transfer dissolved gel mixture or prepared PCR product to the Minicolumn. Incubate at room temperature for 1 minute. 3. Apply vacuum to pull liquid through Minicolumn. Release vacuum when all liquid has passed through Minicolumn.(12,000rpm, 1min) Washing 4.
