Part:BBa_K3292001
T7-LacO Promoter + strong RBS + sialidase + sfGFP + 6x his-tag + double terminator
This device uses Bba_K2406020, Bba_J34801 and Bba_0010 to regulate the expression of a super folding GFP (Bba_I746916). The main objective of creating this device is to facilitate the secretion and characterization of any protein intracellularly produced after adding its nucleotide sequence next to the sfGFP.
Characterization
The characterization of this part included a Bradford assay to quantify the amount of protein present in the medium for each of the proposed constructs. The conditions for the assay are listed below.
The other characterization assay was a fluorescence measurement, where bacteria were growth at 30ºC for 3 hrs. Then 100µl of the grown bacteria were induced with IPTG at 0, 40, 200 and 400 mMm microtiter florescent measures were taken every half an hour for a period of 3 hours. Absorption and emission values were 395/509 nm.
