Trick 1 - The Mode Switcher

The mode switcher, in analogue to a traffic light, combines 3 different interfaces into one powerful device switchable to one another.

Red: Default mode (Veteran, no support needed!)
Yellow: Tour mode (Summary of each and every page in one single map)
Green: Construct mode (A reference diagram of our genetic construction)

Improvements on BBa_K592023 and BBa_K592024

(Blue Fluorescent Protein mTagBFP generators)

The 2011 Uppsala Sweden iGEM team had previously submitted characterization data for parts BBa_K592023 and BBa_K592024. However, we discovered that they did not put a terminator after the mTagBFP CDS. We wondered if the observed fluorescence outputs will be different with versus without a terminator. Therefore, we decided to perform an experiment for comparison. The experimental results showed that the observed fluorescence levels were lowered without a terminator.

Given our results, we would like to caution future users in referencing the relative promoter strengths reported by Uppsala Sweden 2011, as their measured expression levels, generated by parts without a terminator, may not fully represent the true strength of the tested promoters.
