Measure DNA quantity/quality with Nanodrop.
Measure DNA quantity/quality with Nanodrop.
* yield was xxx - xxx ng/ul genomic DNA.
===PCR===
===PCR===
For 50 ul reaction:
For 50 ul reaction:
* xx ul Gotaq
* xx ul mixture of 5 uM forward/reverse Tyro3 primers
* xx ul dH<sub>2</sub>O
* 1 ul of genomic DNA
PCR: 95C for 1min, then 30 cycles of: 95C for 1min, 72C for 2min. (note annealing and extension steps combined into 2 min at 72C).

===Gel===
===Gel===
2% agarose in TAE (2 g agarose in 100 ml TAE, microwave 2 min at 50% power; add 10 ul of SYBR safe 10000x)
2% agarose in TAE (2 g agarose in 100 ml TAE, microwave 2 min at 50% power; add 10 ul of SYBR safe 10000x while cooling). Make mini-gel with 12-tooth comb
load 10 ul of 50bp ladder; 10 ul of PCR product + 2 ul purple loading dye
load 10 ul of 50bp ladder; 10 ul of PCR product + 2 ul purple loading dye
run at 90V for 30 min
run at 90V for 30 min (or 65V for 60 min for sharper bands). Red dye front migrates at about 500bp [CHECK]
===PCR clean-up===

Measure DNA quantity/quality with Nanodrop.
* yield was xxx - xxx ng/ul clean PCR product
===Re-Amplification===
To get higher concentration of DNA for digest, repeat PCR using 1 ul of clean PCR product and clean up.
* yield was xxx - xxx ng/ul clean re-amplified PCR product
===Digestion===
===Digestion===
NEBiolabs says to mix digest with purple dye with 0.5% SDS to separate protein from DNA. SDS may interfere with SYBR Safe, so may need to post-stain the gel.
