RFP Coding Device

Team NRP-UEA_Norwich 2013 added an NdeI restriction site at the start of the RFP coding region of BBa_J04450 using mutagenesis. This was to allow either the promoter region or RFP gene to be excised and exchanged for a different promoter or gene and provide restriction sites for further cloning such as part BBa_K1041002.

Composite part of the following BioBricks:

LacI
R0010
B0034		mRFP1
E1010
B0015

Characterisation

Characterisation of this biobrick involved comparisons with the original Bba_J04450 biobrick by performing transformations, restriction digests and BLAST analysis. We also had our biobrick sequenced.

Transformation

Parts BBa_K1041000 and BBa_J04450 were transformed into Alpha-Select competent E.Coli cells and plated onto LB Agar plates which contained the antibiotic ampicillin. Both plates have colonies that appear red under natural light Fig.1. Therefore the addition of a NdeI site has not effected the ability for the RFP gene to be transcribed.

Restriction Digests

Parts Bba_K1041000 and Bba_J04450 were analysed by restriction digests and run on agarose gels. Both biobricks were cut with NdeI, Fig 2 and PvuII Fig 3.

Sequencing

The biobrick was sent off to a company for sequencing, Fig 3,4,5.The data we recieved back 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. The sequencing with both the forward and reverse primers had over 97% matches with the expected DNA sequence. Fig 6,7
