Applications of BBa_J23107
Evaluation of Anderson promoter J23107 in B. subtilis by iGEM-Team LMU-Munich 2012
This Anderson promoter was evaluated without fused RFP with the lux operon as a reporter in B. subtilis. See the new BioBrick BBa_K823009 without RFP and have a look at the [http://2012.igem.org/Team:LMU-Munich/Data/Anderson Data] from the evaluation in B. subtilis.

iGEM CINVESTAV_IPN_UNAM CHARACTERIZATION OF IGEM DISTRIBUTION BIOPARTS
For contribute to the parts registry our team decided to make the characterization of constitutive promoters, in E. coli, belonging to the family isolated from a small combinatorial library (J23101 , J23102, J23104, J23107, J23108, J2311, and J23115) which were attached to GFP, in psB1C3, to determine promoter activity, using the equipment Victor X3 Multilabel Plate Reader.
Fig. 1 Construction of the promoter J23107 expressing GFP.
Methods
With the selected colonies, an overnight culture was made in M9 media(minimal media supplemented with 0.2% CAA). After 12 hours the culture was transferred to a 96 well plate at a 1:10 dilution (20 μl of culture and 180 μL of fresh M9 medium). OD and fluorescence measurements of the selected colonies were performed at intervals of 30 minutes for 16 h. From the results the PopS were calculated (polymerases per second).
Modeling
The ecuations used for calulated de promoter activity were based on (R. K. Jason et. al 2009).
Results
In the following graphs there is shown the GFP expression in function of th time and the realtive promotor intensity.
With the previous results of the characterization of the promoters there is concluded that the promoter J23107, is the strongest because it produces more RPUs”
