Preparation of pMPMT5+AID construct and PCRs for fusions

Michał K.

  1. Setup of separate cultures from colonies of transformants pMPMT5+AID (liquid LB+tetracycline).
  2. Optimization of conditions for PCR to obtain AID DNA fragment - annealing temperature gradient (from 62°C to 82°C). Fig. 1.
    Primers: AIDlNrH AIDpLinB
    Template DNA: pTrc99A-AID
    Elongation time: 60 sec
    20 cycles
  3. Optimization of conditions for PCR - T7 RNA polymerase for translational fusion; annealing temperature gradient (from 62°C to 82°C). Fig. 2.
    Primers: T7lLinkB T7pXbSal
    Template DNA: E. coli Rosetta genomic DNA
    Elongation time: 4 minutes
    20 cycles
  4. Optimization of conditions for PCR - T7 RNA polymerase for transcriptional fusion; annealing temperature gradient (from 62°C to 82°C). Fig. 2.
    Primers: T7lRBSHi T7pXbSal
    Template DNA: E. coli Rosetta and TOP10 (negative control - Fig. 3.) genomic DNA
    Elongation time: 4 minutes
    20 cycles
  5. Gel electrophoresis of PCR products (there weren't any products for T7 RNA polymerase for translational fusion).

Fig. 1. Gradient PCR products for AID: 1-DNA ladder; 2 to 13-PCR products: In lane 2 is product of PCR reaction with annealing temperature 62°C (the lowest temperature of gradient), in lane 13 is product of PCR reaction with annealing temperature 82°C (the highest temperature of gradient). The lanes between them contain products of PCR with middle annealing temperatures. Fig. 2. Gradient PCR products: upper - for transcriptional fusion, lower - for translational fusion; 1-DNA ladder; 2 to 12-PCR products-border annealing temperatures of gradient: 62°C (lane 2) to 82°C (lane 12) Fig. 3. Gradient PCR products for negative control (Top10 genomic DNA): 1-DNA ladder; 2 to 6-PCR products-border annealing temperatures of gradient: 62°C (lane 2) to 82°C (lane 6).
