Hypothesis 2: Gene L is necessary for phage propagation.
- Here is the quantiluore results from the WP-PCR of 0.1 nM ΦX174 with variable 36-mer primer concentration. ΦX174 1 nM template only control gave 3.34 ng/μL = 0.97 nM. WAIT: Shouldn't this be 0.1 nM? It seems like I am measuring things to be one order of magnitude too high.
- 0 nM - 2.82 ng/μL = 0.82 nM = 0.85 fold amplification
- 100 nM - 245 ng/μL = 71 nM = 730 fold amplification
- 200 nM - 270 ng/μL = 78 nM = 810 fold amplification
- 500 nM - 303 ng/μL = 88 nM = 910 fold amplification
- 1000 nM - 320 ng/μL = 93 nM = 960 fold amplification
- Next step is to optimize primer concentration over a range of 0, 1, 2, 5, and 10 μM (each). I made 10X primer 4 mixes (0, 10, 20, 50, and 100 μM) over this concentration range. 50 μL + 10% WP-PCR reaction.
- 39.6 μL H2O
- 5.5 μL 10X reaction buffer
- 6.88 μL 2mM dNTPs (each) (0.25mM each final)
- 1.875 μL 3.2 nM ΦX174 template (0.1nM final)
- 1.1 μL PfuUltra II fusion HS DNA polymerase
- Aliquot 5×9 μL.
- water = 0 nM
- 1 μL 10μM primer 4 mix (each) = 100 nM
- 1 μL 20μM primer 4 mix (each) = 200 nM
- 1 μL 50μM primer 4 mix (each) = 500 nM
- 1 μL 100μM primer 4 mix (each) = 1000 nM
- Cycling parameters:
- 95 °C 2 min
- 95 °C 20 s
- 58 °C 20 s
- 72 °C 90 s
- Repeat 2-4 an additional 29 times = 30 cycles
- 72 °C 3 min
- 12 °C hold
