Wetlab work

Construction of p+r and re-replacement of BB-pRL1383a MCS

Grace
EtBr stained 2% (L) and 0.8% (R) agarose gels ran at 60V for 2 hours and 1 hour, respectively. Thirty microliters of RE digest reaction were loaded into each well.
  • Ran RE digests from last night on agarose gel
  • C0012: correct vector band ~2.1kb
  • J33207: band at ~700bp (only one enzyme cut -- XbaI did not cut; PstI cuts because C0012 was cut by PstI) and ~850bp (uncut PCR product)
  • nir: ~800bp band (from GFP contaminant in plasmid prep, cut only once) and ~2kb band (??)
  • BB-pRL1383a: ran WAY too much product. Will redo RE digest with 20% of plasmid used. Since J33207 was only cut once, it's assumed BB-pRL1383a was cut only once as well.
  • Extracted C0012 vector band from gel
  • Ligated:
  • plac + rbs (B0034)
  • PCR of J33207
  • RE digested:
  • p+r with EcoRI, XbaI, SpeI, PstI
  • J33207 and BB-pRL1383a with EcoRI and PstI
  • Treated C0012 vector (pSB1A2) with SAP

Construction of Broad-host-Range plasmid

File:PCR 8 30 08.jpg
PCR of rep, p1 omega.
  • PCR:
  • rep(50ul rxn), pRL1383a (template), rep(primers)
  • P1 lytic(50ul rxn), pSB2K3(extracted from BB paper), P1(primers)
  • (+) control: Base Vector + VF2&VR, (-) control: water + VF2&VR
  • Culture: 5mL Terrific Broth + amp100
  • plac+B0030 (1:6):3, 4, 7
  • plac+B0030 :3
  • plac+B0034 (1:6):1
  • plac+B0034 (1:3):3

PCR

Margaret
  • P1 lytic (50ul rxn, pSB2K3(extracted from BB paper), P1(primers), 0.1ug/ml BSA
  • omega (25ul rxn) The last gel had a ladder (so does this reaction, see gel from tomorrow).

Dry Lab
