  • digestion of miMeasure and 6 different synthetic miRNA patterns against endogenous miR122
  • gel seperation
  • gel purification
  • sequencing


12/10/2010

4 miraPCRs for binding sites of miR4286.

  • one PCR with an annealing temperature of 45 degree and 16 cycles
  • second miraPCR with annealing temperature of 57 degree and also 16 cycles
    • nucleotide removal
    • digestion
    • gel seperation
    • gel purification
    • ligation in miMeasure and pSB1C3
    • transformation

13/10/2010

  • pick colonies
  • about 8 hours later: do minipreps
  • send for sequencing


14/10/2010

  • a reasonable
  • Screening of 40 colonies of miR4286 (colony PCR)
  • Screening of 32 colonies of miR320b (colony PCR)


all negative



15/10/2010

ligation of miMeasure construct:

miR-122
miR-122ran
miR-1179
miR-221

each in 0S/0L/10S/10L versions




16/10/2010

transformation of each ligation to TOP10 E.coli

cells were plated on LB-amp plates



17/10/2010

96 colony PCRs - 8 from each plate
ALL NEGATIVE!!!!
