Colony PCR

Reagent

• TaKaRa Ex Taq(5units/μL) 0.5μL
• 10×Ex Taq buffer 10μL
• dNTP Mixture(2.5Meach) 8μL
• Primer F(10μM) 4μL
• Primer R(10μM) 4μL
• Template(E.coli DH5α)

→Reflection:We Took E.coli too many.You should take less E.coli.
Conditions of the thermal cycler

1. 95°C(5min)
2. 94°C(30sec)
3. 61°C(30sec)
4. 71°C(40sec)
5. 72°C(1min)
6. 4°C(Save)
   • 2~4:35cycle→Reflection:The number of cycles was less.So,We increased The number of cycles in 8/11.(50 cycles)

Date:8/11

The purified DNA

1. Electrophoresis
   • Marker:pigment(buffer) 1μL,DNA molecule 2μL,TE buffer 3μL
   • Sample:pigment(buffer) 1μL,sample 5μL
   • Gel concentration:1.2%,Migration time:30min

→Reflection:Band was less.

1. Storage

PCR Product

1. Electrophoresis
   • The gel check and cut
2. DNA purification
3. Confirmation of electrophoresis
4. PCR
   • 50cycle
5. Storage

Date:8/13

Confirmed of electrophoresis by PCR product and Ligation of the TA vector

1. Electrophoresis
   • Gel concentration:1.2%,Migration time:30min
   • Marker:Flash Gel 5μL
   • Sample:pigment 1μL,sample 5μL
2. Check and Colony PCR
3. Add to TA vector
   • PCR product 2μL
   • pMD20-Tvector 1μL
   • D₂W 2μL
   • Ligation Mighty Mix 5μL
4. Heat insulation(16°C,30min)
5. Storage(-20°C)

Date:8/14

Transformation

1. Put competent cells on ice(10~15min)
2. Add Ligation reaction solution(10μL) and tapping
3. On the ice(30min)[Transformation]
4. Add LB medium(0.7mL)
5. Incubate(60min,37°C)
6. Add X-gal(40μL) and ampicillin(10μL)[200μg/mL] on LB agar medium(IPTG)
7. Add one incubated(100μL)
8. Cultivation(overnight)
