    To add our keratinase genes with promotors we transformed BBa_J23115, BBa_J23119 and an inducible pBAD promotor BBa_K206000 and cut cleaned up plasmids with EcoR1 and Spe1 for Standard Assembly.
 +
    After digest with second enzyme, for J23115 and J23119 only plasmid backbones were detected.
 +
      In lines of K206000 two fragments were detected, as expected (insert and backbone) (figure ).
