PCR Protocol

After primers are designed and the correct gene can be isolated, PCR is used to amplify the selected DNA for further use in our system.

Material:

Primers (FWD, RVS)

PCR Supermix

Parent plasmid


Method:

1. Measure the concentration of the primers and the parent plasmid as follow: Do a dilution of 50:1 with 1EB buffer [ do 98ul tris into 2 ul of DNA ] Use the below formula to find the concentrations

Conc. (ng/ul) = OD reading * dilution factor * DNA factor = OD reading * 50 * 30

2. Mix 90ul of PCR supermix with 80ng of each DNA, 200nM of each primer

3. Put 90µl in 0.5ml tubes.

4. Find the length of the PCR product from Vector NTI

5. For each Kb need 1 min for step 4/5

6. Run the PCR program

7. Put finished tubes in -20


PCR program:

CTRL Tube (controls temperature based on tube volume)

LID = 100

WAIT AUTO (waits till lid is 100 before starting program)

1. temp{94} for 30 seconds.

2. temp{94} for 30 seconds

3. temp{55} for 30 seconds

4. temp{72} for x min. (1min/kb) (68C for fragments > 5 kb)

a. perform 30 cycles of steps 2-4

5. temp(72) for x min. (1min/kb) (68C for fragments > 5 kb)

6. temp(10) forever


All temperatures are in degree Celsius.
