1. Set up PCR Reaction:

2. Run PCR Conditions:
a) Temperature95 °C , Duration00:02:00
b) Temperature95 °C , Duration00:00:30
c) Temperature60 °C , Duration00:00:30
d) Temperature72 °C , Duration00:02:00
e) Repeat step B-D 35 times
f) Temperature72 °C , Duration00:10:00
g) Temperature4 °C , hold
*Annealing Temp and Extension time will differ based on PCR design
3. After reaction, take Amount5 µL of product and add Amount1 µL of gel loading buffer and run on 1% agarose gel to make sure there is a correct PCR product.
4. Add Amount5 µL of Cutsmart buffer and Amount1 µL of DpnI to the reaction and incubate at Temperature37 °C for Duration00:15:00 . This is remove the plasmid template from mixture.
5. Purify Band from gel with Promega Wizard SV Gel and PCR Purification Kit (A9282)
b) Weigh DNA gel fragment and add Amount10 µL of Membrane Binding Solution per 10 mg of gel slice.
c) Incubate mixture at Temperature65 °C for Duration00:10:00 or until gel is completely melted.
d) Add melted gel mixture to SV minicolumn in Collection Tube and incubate at room temperature for Duration00:01:00 .
e) Centrifuge at max speed for Duration00:01:00 . Discard flowthrough and reinsert column into tube.
f) Add Amount700 µL of Membrane Wash Solution. Centrifuge at max speed for Duration00:01:00 . Discard flowthrough and reinsert column into tube.
g) Add Amount500 µL of membrane wash solution. Centrifuge at max speed for Duration00:01:00 . Discard flowthrough and reinsert column into tube.
h) Spin empty column for Duration00:01:00 at max speed to remove excess ethanol.
i) Transfer column to labelled Amount1.5 mL tube and add Amount35 µL of NF H20. Incubate for Duration00:01:00 at room temperature.
j) Centrifuge at max speed for Duration00:01:00 . Keep eluate and store at Temperature-20 °C .
