== '''In well MDA using genomic DNA''' ==
''Use MDA to compare results to pWGA''
*Prior to beginning, create NS and ALS buffers
*ALS Buffer:  82 uL H20, 10 uL 1M DTT, 8 uL 5 M KOH
*NS Buffer:  3 mL H2O, 3 mL 2M Tris, 4 mL 1N HCL
*Make sure an even mix of the 2 buffers has a pH of 7-8 before moving on
*Clean down hood with ethanol and UV tubes, arrays, gaskets, etc for 10 min
*Use e coli gDNA with initial conc.  10^6 cell/uL
*Create the following mix:  38uL .1% agarose, 12 uL gDNA, 6 uL C12 N6 labeled beads, 4 uL 3% BSA
*Make another mix as an NTC (Use agarose instead of gDNA)
*Add 3 uL of each mix to 2 separate squares and let settle for 5 min
*Add 3 uL of ALS buffer to each and sit for 3 min
*Create the following master mix while waiting:  15 uL 200 uM N6 primer, 7.5 uL 10x buffer, 17.1 uL H2O, 2.4 uL 25 nM dNTP, 3 uL Phi 29.  This master mix is enough for 3 reactions
*After 3 min, add 3 uL of NS buffer to each square to neutralize
*Add 16 uL of master mix to each.  Incubate at 30 C for 4 hr then 85 C for 3 min.
