PCR protocols
CheZ (Taq pol)
CheZ (Phusion pol)
Conditions for one reaction (25 uL):
-1x HF buffer (5 uL 5x buffer) -Forward primer (1.5 uL) -Reverse primer (1.5 uL) -dNTPs (0.5 uL) -Phusion (0.25 uL) -mQH2O (15.25 uL) -Template (1 uL)
Cycling protocol ("cheZ"):
1. Initial denaturation @ 98C for 4 mins (1 cycle) 2a. Denaturation @ 98 C for 30 sec (35 cycles for step #2) b. Annealing 47.0C for 30 seconds c. Extension @ 72C for 30 sec 3. Final extension @ 72C for 7 mins (1 cycle) 4. Hold at 4C

Competency
Squeeze 'n Freze Gel Extraction
-Run the sample you wish to extract on a TAE-Agarose Gel -Cut out the band you wish to purify -Incubate in 3 gel volume 0.3 M NaAc (pH 7.0) at room temperature for 30 minutes. -Make your own spin column from a small microfuge tube with a hole cut out of the bottom, stuffed with glass wool. This tube should be inserted inside a 1.5 mL microfuge tube. -Transfer the solution to the spin column. -Freeze the tube in liquid Nitrogen for 1 minute, then spin at full speed for 15 minutes. -Precipitate the DNA in Ethanol. Remove the supernatant. -Wash in 75% Ethanol. Remove as much ethanol as possible. -Centrifige for 5 minutes then, remove the rest of the ethanol. -Let pellet to air dry for 10 minutes, this allows all ethanol to evaporate off. -Resuspend in TE Buffer (pH 8.0), 10 uL. -Quantify either by Gel or UV Spec. -Proceed with ligation.
