      • 11.5 uL water
      • 12.5 uL OneTaq Master Mix
      • 0.5 uL 10uM fwd primer
      • 0.5 uL 10uM rev primer
    • 95°C (2:00) | 95°C (0:07),  60°C (0:10),  72°C (1:06) [10 cycles] | 95°C (0:07), 50°C (0:10), 72°C (1:06) [18 cycles] | 72°C (5:00)
    • 25 μL reaction volume, 28 cycles
  • Ran gel on the Tet RTW-PCR troubleshooting iteration
  • Gel Extraction of the Linear Tet Backbone
    • Gel Extracted 1 (lane 4)  and 3 (lane 8)
    • #1: weight of gel excised: 106.9 mg
    • #3: weight of gel excised: 163.4 mg
    • Used Epoch kit & team-modified procedure

Sara

  • Ran a colony PCR on the GFP and mCherry/storage vectors with Shu
    • Used Vf and Vr primers, 25 uL total volume, 12.5 uL OneTaq MM. Ran 3 controls: No DNA- the PCR reaction contained everything but template DNA. Positive control- DNA straight from the iGEM kit containing RFP, which is a similar size to our desired inserts (J04450 in pSB1K3), and Backbone- Which was only the pSB1K3 backbone
    • 12.5 uL OneTaq MM
    • 0.5 uL BB Vf Primer
    • 0.5 uL BB Vr Primer
  • Ran a gel on the colony PCR
    • The results look like the products are all too small to say that the inserts were successfully placed into the storage vector, but we didn’t run any controls, so we can’t be absolutely positively sure
  • Helped Tyler transform the Cas9 Gibson product into some cells

Tyler

  • Ordered gRNA constructs
  • Designed a lot of the bioinformatics gRNA project
  • Transformation + Helped sara w/her colony PCR
