Preparation of alpha+A conctruct

Antoni

1. Gradient PCR on alpha+A PCR products with AlphaL+SacI and AP+NotI primers.
2. Gel electrophoresis. Again without satisfying results.
3. Third PCR on alpha+A. This time two temperatures of annealing (68°C and 72°C) and gradient of DMSO.
4. Gel electrophoresis (Fig. 1).
5. Gel-out of proper 1000 bp band.
