Fluoro-Max 绿色荧光粒子标志物微球

在评估局部缺血时，多种染料与微粒标志物被用来标记“风险区”。已使用过的标记物有埃文斯蓝、India Ink与荧光素。但是这些染料会很快迁移遍布至整个组织器官，使得风险区很难被辨别出来。而荧光微粒标记物则十分有效，因为微粒会暂停于毛细血管中，在荧光灯下很容易被识别。
荧光标记物微粒由含有特殊荧光染料的聚合物合成，这种荧光染料采用手持式UV 灯(Wood's Lamp)即可被有效激发。

这种荧光是一种明亮的黄绿色。这种微粒是球形的，直径为 1-10 μm，密度为 1.05 g/cm³。因此此种微粒很容易悬浮于液体介质中。

这种微粒被重度染色，因此具有很容易被识别的荧光强度。此微粒在白光下是不可见的，因此可进行非风险组织是否梗死的检查。

因为染料是着床于微粒的内部的，因此不会发生颜色渗滤或造成其它物质被染色。

Effectively mark the “risk zone” in evaluating regional ischemia with Thermo Scientific™ Fluoro-Max Green Particulate Marker Particles, brilliant yellow-green particles that lodge in the capillaries.  Easily seen under fluorescent illumination, these particles are made of polymer containing a fluorescent dye that excites efficiently with a handheld UV lamp (i.e., Wood's Lamp). They are spherical, 1-10μm in diameter, and have a density of 1.05g/cm³, which makes them easy to suspend in an aqueous medium.

Various dyes and particulate markers have been used to mark the “risk zone” in evaluating regional ischemia. These 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 viewed under fluorescent illumination. 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.

Recommended for:

Myocardial infarction studies and other biological research. Not to be used for instrument calibration.
