Put all the parts (digested and undigested) on gel. In J01-J04, no difference in band size was detectable, because the cut off part is only a few bp. The vector showed 1 band when uncut and 2 bands when cut. <br/><br/> | Put all the parts (digested and undigested) on gel.

After 1 hours of growing in SOC medium, 35 ul and 175 ul was plated containing Cm antibiotics, then incubated at 37°C. <br/> |

Every picked colony was grown over night in LB containing Cm antibiotics in the 37°C climate room rotating at 160 rpm. <br/> |

PCR gave an inconclusiv result. PCR was repeated in the morning, with the non-red strains: Only 1 strain of J04 contained the insert. <br/> |

- | The sequences of BBa_J01 and BBa_J04 | + | The sequences of BBa_J01 and BBa_J04 showed that J01 was the right insert of pp1262 and intergenic region (including RBS). J04 had the right sequence except for an inconsistency in the promoter region. This is probably a result of a mistake in the primer design. <br/> |
- | Cut the isolated BBa_J01 and BBa_J04 vectors with EcoRI and SpeI. | + | Cut the isolated BBa_J01 and BBa_J04 vectors with EcoRI and SpeI. Added these restriction enzymes to BBa_J23100, a biobrick containing a reporter gene, with its active promoter between E & S. By inserting the J01 or J04 promoter, the reporter should in theory only work if the added promoter is active. By using alkaline phosphatase, the chance for self-ligation became much smaller. <br/><br/> |

The PCR showed inserts in 1 of each colony (1.2 and 4.1). Also made stocks of these two transformed strains. <br/><br/> |
