Part:BBa_K731700

Platform for terminators analysis under the control of T7 promoter

We used this part to test terminators: the two subsequent proteins allow to quantify the termination efficiency as the ratio between Venus's and Cherry's fluorescence. The vector is pET21b, that contains lacI, t7 promoter and ampicillin resistance gene. The two fluorescent proteins have partially overlapping emission spectra, thus the fluorimetric measures should be taken with these parameters, to avoid interference between the two: Venus excitation: 485nm, Venus emission: 528nm Cherry excitation: 528nm, Cherry emission: 615nm We inserted the prefix-suffix linker between the two proteins, to allow terminator characterization.
