===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

+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.
