Team NRP-UEA_Norwich 2013

Team NRP-UEA_Norwich 2013 designed this part to contain the promoter sequence AntG, where the unique sigma factor AntA binds to activate transcription of the neomycin resistance gene. There is a Nde1 resticition site between the promoter and gene to allow either to be removed and exchanged for a different promoter or gene. This facilitated cloning of the biobrick Bba_K1041002

Characterisation of this biobrick involved sequencing, restriction digests and BLAST analysis.

Restriction Digest

Part Bba_K1041001 was cut with enzymes XbaI and NdeI and compared to the uncut DNA. Fig 1

Fig 1:Lane 1 contains uncut Bba_K1041001 and Lane 2 Bba_K1041001 cut with XbaI and NdeI.

Sequencing

The biobrick was sent off to a company for sequencing and the data we received back Fig 2,3,4 showed the DNA is of good quality.

BLAST Analysis

The data we recieved back from the sequencing company was aligned using BLAST with the expected DNA sequence Fig 5,6. The sequencing with both the forward and reverse primers had over 98% matches with the expected DNA sequence.
