Restrictions

  • Resticted (total 60µl DNA) K314100 in psb1c3 with spe1 and Pst1
  • Resticted (total 60µl DNA) Oxytocin in puc19a with Xba1 and Pst1
  • Resticted (total 60µl DNA) NEC1puc19a with Xba1 and Pst1
  • Set 12 µl aside from each reaction and gel extracted(GEX) the remaining 48ul
  • Combined heat killed restriction mixtures into ligation mix from NEB using NEB protocol, left at room temperature for 10 mins then heat killed for 20 mins at 80
  • K314100 – psb1c3 (s,p), with: Oxytocin (x,p)
  • K314100 – psb1c3(s,p), with: NEC1 (x,p)
  • GEX K314100 – psb1c3(s,p), with: GEX Oxytocin (x,p)
  • GEX K314100 – psb1c3(s,p), with: GEX NEC1 (x,p)

Transformation

  • Transformed ligations into 20ul high efficiency Dh5a cells and 50ul lab made competent Dh5a
    • K314100 – psb1c3 (s,p), with: Oxytocin (x,p)
    • K314100 – psb1c3(s,p), with: NEC1 (x,p)
    • GEX K314100 – psb1c3(s,p), with: GEX Oxytocin (x,p)
    • GEX K314100 – psb1c3(s,p), with: GEX NEC1 (x,p)
  • Plated on CAM plates
  • Results: Only the 20ul non gel extracted Dh5a E. coli high efficiency cells grew

Picked Colonies

  • Date: June 4, 2013
  • Picked 10 colonies from each plate
  • Grew over night in LB and mini prepped
  • PCR-ed with Vf2 and Vr primers no results as shown
  • Gel on June 4, 2013
  • Picked 6 Oxytocin colonies and 5 NEC1 colonies grew overnight in LB – minipreped and restricted all colonies picked so far at E,P and ran on gel results concluded as ligations did not work since a band is seen at ~500 bp size of the promoter construct K314100 but not with oxytocin or NEC1
  • Gel on June 4, 2013

    • J23108-J06702
    • J23113-J06702
    • K314100-oxytocin neurophysin1
  • June 12th results arrived
    • J23100-J06702- positive for J06702 but no promoter found
    • J23108-J06702- positive for J06702 but no promoter found
    • J23113-J06702- positive for J06702 but no promoter found
    • K314100-oxytocin neurophysin1 – Positive results full sequence found

Transformation of OXY into BL21

  • Date: June 13, 2013
  • Transform minipreped plasmid DNA of K314100 –Oxytocin Neurophysin1 in psb1c3 into 15ul of Bl21 E.coli cells
  • Let grow over night at 37 on CAM plates

Restricted and Ligated and Transformed

  • Date: June 13, 2013
  • Restricted K314100 spe1 and pst1 and Nec1 at xba1 and pst1 for 1 hour at 37 followed by 20 min heat kill at 80
  • Mixed restrictions in ratio of 10ul NEC1 and 2ul k314100 in psb1c3 let sit in ligation mixture for 10 mins at room temperature followed by 20 min heat kill at 80
  • Transformed 2ul into 20ul of DH5a E.coli highly competent cells, incubated overnight at 37

Picked Cells

  • Date: June 13, 2013
  • K314100 – Oxytocin neurophysin in psb1c3 grew in Bl21 from last nights transformation, picked 4 colonies and grew up in 5ml of LB overnight at 37 with shaking
