Team Allergy

  • amiRNA fragment production appears to have worked at every Tm we tried (click images for details):

  • V9/V10
    • Diagnostic digest of our gel :

(Should see ~ 7kb band and an 840 band)

    • Realized that we hadn't gel purified our inserts
    • Gel purification of inserts (entire ihpRNA parts)

Team Fence

PCR of VP16.3

60μL reaction:

  • 1.5 μL pfx polymerase
  • 3μL DNTPs
  • 18μL enhancer buffer
  • 1.5μL MgSO4
  • 3μL 1/10 dilution VP16.Hind.Fwd
  • 3μL 1/10 dilution VP16.Rev

Digestion of Gal-EcR

BamH1 and Nco1 12 digestions, one for each Gal-EcR miniprep Each:

  • 1μL BamH1
  • 1μL Nco1
  • 1μL 10x FD green buffer
  • 2-7μL EcR-Gal miniprep
  • 5-0μL DH2O, to bring total volume to 10μL

Confirmation Digests

  • Ran confirmation digests of miniprepped J45004-1, J45004-2, J45017-1, J45017-2
    • Digested approximately 500ng with xbaI/speI
  • Ran confirmation digests of miniprepped Miraculin N strep+stop and V24, Miraculin C strep+stop and V24, Brazzein N strep+stop and V24, Brazzein C strep+stop and V24.
    • Digested 400-500ng with notI/speI

Retry Ligating j45004 and v0120

  • Used PCR purified J45004 that had been previously digested with xbaI/pstI
  • Used v0120 from Team Vector that they had digested with xbaI/pstI and used in a successful ligation
  • 3:1 insert to backbone ration used in ligation
    • 52ng of insert and 50ng v0120 backbone
    • J45004 insert is 1100 bp
  • Transformed and plated on LB+Amp plates and left overnight
