Part:BBa_K314101
Designed by: Tomas Huber, Justin Siegel Group: iGEM10_Washington (2010-10-08)
Low constitutive expression cassette
Low constitutive protein expression insert includes f1 origin K314110, a high expression promoter J23114, and the Elowitz standard RBS B0034. When ligated with a protein coding sequence at the SpeI site the scar site created will create proper spacing for protein expression.
Usage and Biology
|
BBa_E0040 (GFP) was inserted between S and P using standard BioBrick assembly. The resulting constructs were grow in DH5a (constitutive promoters BBa_J23100 or BBa_J23114, as well as inducible promoter BBa_R0011) or BL21(DE3)* (T7 promoter, BBa_K314104) cells overnight at 298K in either the presence or absence of 0.5mM IPTG. The cells were harvested, washed in PBS, and then fluorescence for the whole cells was measured on a fluorometer (ex. 485, em. 525) and normalized to cell density (OD600). Cells that did not contain GFP were used as a blank. As observed, the addition of IPTG significantly increased the observed fluorescence of the cells. |
