Duke Fluoro-Max熒光標記粒子-綠色
Fluoro-Max綠色熒光標記粒子是非常有用地，因為把這些熒光粒子嵌入****中，*以在熒光光源的照射下，很容易的看到其發(fā)出來的綠色熒光
Particulate Markers (for myocardial infarction studies)
Various dyes and particulate markers have been used to mark the “risk zone” in evaluating regional ischemia. Markers that have been used include Evans Blue, India Ink
ａnd Fluorescein. However, these dyes tend to rapidly migrate throughout the tissue making the risk zone difficult to identify. Fluorescent particulate markers are effective because they lodge in the capillaries and are easily visualized under fluorescent illumination.
The fluorescent marker particles are made of polymer containing a special fluorescent dye that excites efficiently with a hａnd held UV lamp (i.e., Wood’s Lamp).
The fluorescence is a brilliant yellowgreen color. The particles are spherical, 1-10 μm in diameter, and have a density of 1.05 g/cm3. This makes them easy to suspend
in an aqueous medium.
The particles are heavily loaded with dye, resulting in a very strong fluorescence that can easily be seen. They are invisible under white light, allowing the non-risk tissue to be examined for infarction.
Since the dye is embedded in the interior of the particles, it does not leach out or cause indiscriminate staining.
