Things we did today
Wetlab work
Transformation
- Margaret
- Transformation of I14032 into Db3.1
Colony PCR
- Margaret
- Verifying the inserts of two I51020 (the base vector) and one colony of pSB1A7 (an insulated vector with high copy #)
PCR amplification of pRL1383a
- Margaret
- The omega region from pSMC121 and the rep/mob region are giving primer dimers and misamplification respectively. I am trying a gradient PCR from 49°C to 55°C to see if this will fix the problem.
PCR for BB-pRL1383a construction/verification
- Grace
- PCR of BB-pRL1383a (from plasmid prep) using VF2 & VR_B0034 primers to verify B0034 insert and MCS replacement
- PCR of B0034 with HindIII and BamHI primers in case we need to redo BB-pRL1383a construction
- Maintained everything on ice this time
- Used 0.5μl plasmid in PCR reaction
- Annealing at 55C
- Extension for 30 sec. at 72C
Plasmid preps
- Grace
- Resuspended plasmid preps in 30 μl TE and checked concentrations on nanodrop spectrometer
- nir+B0034 = 13.6 ng/μl
- GFP+B0024 = 9 ng/μl
- GFPf+B0024= 7.1 ng/μl
- BB-pRL1383a = 166.3 ng/μl
- Restriction digested nir+B0034 plasmid prep to verify insert (GFP and GFPf constructs were verified last week)
- Digested w/ EcoRI and SpeI so we can extract from gel if insert is correct
- Incubated at 37C for 2 hours
GFP(f) + tt constructs
- Grace
- Restriction digested GFP and GFPf w/ EcoRI and SpeI in 50 μl reactions for 3 hours
- Restriction digested B0024 (tt) with XbaI then EcoRI for 3 hours total
- Ran on an EtBr stained 3.8% agarose gel alongside GFP+B0024 ligation from 7/22 to see if ligation was successful (and the problem was with the colony we picked)
- Gel purified bands and ligated GFP(f) with B0024
- Ligation reaction incubated at room temperature for 2 hours.
Transformation of GFP(f)+tt constructs into DH5α
- Krystle
Drylab Work
Primer Design
- Margaret
- I want to design primers for some replication proteins + origin from pSB2K3
