* Concentration needed to dilute the primer E34K reverse was calculated with the below information: | |||
Melting Temperature in 50mM NaCl=62.2°C | |||
Molecular Weight=16,877.0g/mol | |||
Amount of miligrams present=0.58mg | |||
Strand: 5'-ATG TTA AATCTA AAT GGC AAT GTA ATT TAA CTT TGG GAA TTC TTC TTC ATA TTT C-3' | |||
GC content=27.2% | |||
nmoles/OD260=1.9 | |||
ug/OD260=31.6 | |||
Ext. Coefficient: 534,6000 L/(mole·cm) | |||
Amount of moles=34.4moles | |||
* The concentration of primer E34K reverse was calculated, and amount of diluted primer needed for PCR was determined the following way: | |||
Target concentration: 100ng/uL | |||
0.58mg=0.58·10<sup>6</sup>ng | |||
0.58·10<sup>6</sup>ng / 1000μL H<sub>2</sub>O = 580ng/μL | |||
100ng/uL x 1000uL / 580ng/uL = 172.41μL | |||
**1mL of sterile water was added into reverse primer, making the concentration of the reverse primer 3.4×10<sup>4</sup>M. | |||
**172.41μL of 3.4×10<sup>4</sup>M reverse primer was pipetted into a 1.5mL microcentrifuge tube, and 827.58μL of sterile water was added to make up a total of 1mL 100ng/μL reverse primer. | |||
**100ng/μL reverse primer was made at 1mL. | |||
* With 100ng/μL of forward primer of E34K made, PCR solution was made with the following reactants: | |||
1μL of forward E34K primer | |||
1μL of reverse E34K primer | |||
1μL of ADA wild strand | |||
0.4μL of 25mM dNTPs | |||
5μL of 10x cloned Pfu buffer | |||
40.6μL of sterile water | |||
1μL of 2.5μL Turbo DNA polymerase | |||
**Turbo DNA polymerase was added last and right before PCR solution was placed on Thermocycler | |||
**Two of PCR solutions were made | |||
*The Thermocycler was programed in the following way to detach and reanneal DNA to allow DNA amplification: | |||
Heating for 2minutes at 95°C | |||
30 times of the following procedure: | |||
Heating for 30 seconds at 95°C | |||
Cooling for 30 seconds at -5°C | |||
Reheating back for 1 minute at 72°C | |||
Maintaining temperature at 72°C | |||
Cooling back to 0°C for plasma stability | |||
* New sets of Au/BSA solutions was made with the following ratios: | |||
60, 80, 100, 120, 128, 130, 132, 133, 134, 136, 138, 140, 160, 170 | |||
**Stock solution of BSA at 3μM and HAuCl4 at 26mM was made the following way: | |||
Molecular weight of BSA: 66,000g/mol | |||
0.0398g of BSA in powder form was weighted out and diluted in 20mL of water | |||
0.0398g BSA ÷ 66,000g/mol = 3.01×10<sup>-5</sup>M = 30.1μM BSA | |||
**Stock for HAuCl4 from [[User:Keyun Wang/Notebook/Experimental Biological Chemistry I/2012/10/03|10/03/12]] was used due to long shelf life | |||
* The amount of HAuCl4, BSA, and water was calculated via excel to make Au/BSA solutions with above ratios, show in table below: | |||
