Week 11: July 24-31, 2011

  • Monday:
    • Regenerate Nickel columns
    • Incubate sample with beads
    • Survival assay
    Tuesday:
    • Survival Assay again
    • Elution from loose beads + SDS
  • Wednesday:
    • Run flow-through through beads again
  • Thursday:
    • Researched ice-affinity purification
    • Dialyzed sample
  • Friday:
    • Planned/mapped out next 4 weeks
    • Took dialyzed bag with purified eGFP-RiAFP and divided it into 12 eppendorfs, containing 1 mL each. Flash-froze tubes in liquid nitrogen, then quickly used a hot edge to poke holes into top of eppendorfs to allow sublimation. Tubes then placed in lyophilizer for 3 nights.
  • Saturday:
    • Began cloning all pSB1AK8 constructs into pSB1C3 for parts submission (G3, H1, RiA, RiG, T2, Z2?) by digesting those 6 constructs and linearized pSB1C3 with EcoRI, PstI
    • Also, PCR amplified eGFP segment from original eGFP-RiAFP plasmid to use as a control for survival assays
    • Digested PCR fragment with eGFP with XbaI, PstI, and digested BBa_I712074 (strong T7 promoter) with SpeI and PstI
    • Gel extracted all digested pSB1AK8 constructs using kit, gel visualized with SYBRSafe (digestion seemed successful)
  • Sunday:
    • Ligated gel-extracted pSB1AK8 fragments with pSB1C3; ligated eGFP PCR fragment with BBa_I712074
    • Transformed ligations into DH5alpha cells, plated them
