We labeled a contrast as significant if a single-voxel threshold of p<0.005 (uncorrected) was met in at least five contiguous voxels.
Gadolinium and ferric oxide are two common cell labeling contrast media used during MRI [ 6].
Exogenous label contrast agents, such as fluorescence dyes, can solve the contrast problem, but they may make the living cells phototoxic and influence the cellular behavior [ 2].
Not only have we improved the labeling contrast, but we have also shown targeted delivery of a model cargo (TAMRA or QSY9) into tumor cells in vivo, encouraging the further development of pHLIP for therapeutic applications in drug delivery.
Rapid developments at all levels of microscopy experiments – from improvements in sample labelling, contrast, illumination, resolution, signal detection and data processing have all occurred and there is every reason to expect that these advances will simply continue.
The significant reduction of the BSA label contrast within the central zone of fibrin formation indicates that the BSA label is not preferentially immobilized at the wound site by blood coagulation due to its lack of reactivity with fibrin and TGs.
Hybridizations were performed with males and females of the same genotype, labeled in contrasting dyes, hybridized to the same chip.
"A Tale of Two Cities," by Charles Dickens, because people are always labeling the contrast between rich and poor in New York City a tale of two cities, when Dickens was actually writing about Paris, London and the French Revolution.
Images were cropped, labelled, and contrast adjusted using Adobe® Photoshop® CS software.
To evaluate contrast enhancement of HeLa cells labeled with lipophilic contrast agents 1– 3, MR images of cell pellets were acquired at 7 T. HeLa cells were incubated with either 20 μM contrast agent or 90 μM normalized Gd III).
Two sets of images are shown; higher magnification dual-labelling with calcofluor (blue) and antibody labelling contrast-enhanced by changing the hue angle to a reddish-pink colour, and antibody immunofluorescence labelling in green.
