results:
AC138130_5: ok, but increase Ta to 53°C + use less cycles
AC152423_24: fine → final conditions: 35 cycles, Ta=50°C
AC175826_16: fine → final conditions: 35 cycles, Ta=53°C
AC146866_11: better, but still additional bands → increase Ta to 55 and 57°C
from yesterday:
AC148405_5: make new primers
AC158504_5: Ta=50°C ok, but use less cycles → try 32 and 29
