Sentence examples for level of fret from inspiring English sources
Placing fluorescent donor and acceptor groups on the binding protein and fragment reduces the background level of FRET of the unbound sensor, resulting in a ratiometric FRET response that is expected to be strong and reproducible from protein to protein.
However, the fact that the level of FRET increases as predicted when GFP is placed closer to the DR3 His10 tag coupled with the observation that FRET is being measured across a distance of over 1000 amino acid residues in the RyR1 primary sequence demonstrates the utility of this technique in structural mapping of the RyR.
The level of FRET decay is a function of the amount and infection duration of the inoculated virus as measured by a fluorometer assay.
This level of FRET (53%) was higher than the level of FRET observed (20%) between GFP at position 1 and Cy3NTA bound to the His10 tag at DR3.
As a result, the level of FRET rapidly and significantly decreases.
When co-expressed, CXCR4CFP and CCR5YFP displayed a high level of FRET signal, indicating that CXCR4 and CCR5 formed heterodimers.
Further, significant levels of FRET signal was delayed by about 60 minutes.
These findings are consistent with predicted levels of FRET between these points estimated from cryo EM maps localizing the N-terminus, amino acid 423 and amino acid 1903 [3], [22], [27], positions roughly analogous to the locations of GFP (amino acid position 1, 618) and the His10 tag (position 1861) in the present study.
Of the 28 imaged cells, 25% show high FRET efficiency (>3-fold change; red border around images), 39% show moderate FRET efficiency (2 3-fold change; blue border), and 36% show background levels of FRET (<2 3-foldhange; purple border).
As previously observed with wild-type PER and TIM, we detected high levels of FRET in S2 cells expressing PER and TIMΔNLS shortly after their induction, and FRET persisted for several hours.
Furthermore, we show constitutively high levels of FRET, comparable to ligand-bound wild type IGF1R between subunits of the H905C variant when its cytoplasmic domains are substituted with a FRET donor-acceptor pair.
