Chris and I will be taking responsibility for MIDAS from here on.
Started overnight MDA with Jeff and Chris observing. Loaded 8 arrays with PGP-1 chromosomes.
- 2 conditions:
- 4 arrays with protease (trypsin)
- 4 arrays, standard protocol except no freeze thaw
Did not image prior to ALS because chromosomes were expected in every well due to high concentration.
- Modification to standard protocol for protease treatment:
- Load 3 ul chromosomes. Add coverslip, let sit 10 min @ RT
- Load 3 ul 0.25% trypsin (1X) into protease condition arrays. Cover and let sit 5 min @ RT
- Load 4.5 ul ALS into all arrays. Cover and incubate 10 min @ 40 degC in thermocycler with plate adapter
- Load 4.5 ul NS into all arrays.
- Protocol based on Quake haplotype paper (Fan et al. 2010 NBT)
- Protease condition master mix(per rxn/array):
- 15 ul template
- 1 ul 1 mM N6*
- 1 ul 25 mM dNTP (Epicentre)
- 2.3 ul 10X Phi29 buffer
- 0.1 ul 50X SYBR Green
- 1 ul 23X protease inhibitor (cOmplete)
- 1 ul H2O
- Total = 11.2 ul
- No protease condition received 11.2 ul standard MDA master mix

Extracted and processed 14 samples + 2 NTCs (no extraction)
1 NTC showed large amount of amplification during blue/orange PCR, more than all other samples. Reagent contamination would have been seen in all samples.
- 2 samples confirmed positive on gel. Nextera indexes #28 and #32.

Chris started overnight MDA with Jeff and I observing. Loaded 8 arrays with neuronal nuclei.
