一般說明
葡聚糖是葡萄糖酐聚合物。 由大约95%的α-D-(166)键组成。 剩余的(163)键是葡聚糖的分支。分支长度的冲突数据意味着平均分支长度小于三个葡萄糖单位。但是,其他方法表明存在大于 50 个葡萄糖单位的分支。已发现的天然葡聚糖分子量(MW)在900万至5亿范围内。MW较低的葡聚糖分支略少,MW分布范围较窄。MW大于10,000 的葡聚糖表现得似乎它们是高度支化的。 随着MW的增加,葡聚糖分子的对称性增强。 MW为2,000至10,000的葡聚糖表现出可膨胀线圈的特性。 MW低于2,000的葡聚糖更像棒状。葡聚糖的分子量通过以下一种或多种方法测定:低角度激光散射、尺寸排阻色谱法、铜络合和蒽酮试剂、比色法还原糖测定和粘度。
應用
FITC-葡聚糖被广泛用于运用显微荧光法进行微循环和细胞通透性研究。 FITC-葡聚糖被用于植物细胞壁孔隙度和毛细血管通透性研究。研究表明,血浆蛋白不与FITC-葡聚糖结合。
用异硫氰酸荧光素标记的葡聚糖可用于动物的灌注研究。
荧光素-葡聚糖,2000 kDa,用于使用小型集成荧光显微镜对活跃小鼠的脑微血管系统进行体内成像。FITC-葡聚糖,2000 kDa(FD-2000)在心血管、微循环、灌注和细胞膜通透性研究中用作荧光通量示踪化合物,可实现对血流、膜损伤、血管引流和肾脏清除等过程进行检测。 荧光素-葡聚糖,2000 kDa,用于使用小型集成荧光显微镜对活跃小鼠的脑微血管系统进行体内成像。 FITC-葡聚糖被用于植物细胞壁孔隙度研究。
準備報告
Sigma通常以25 mg/ml或更高的浓度测试FITC葡聚糖在水中的溶解度。 溶液应避光保存。 在体内,FITC-葡聚糖稳定24小时以上。

Clinical studies have revealed a strong link between increased burden of cerebral microinfarcts and risk for cognitive impairment. Since the sum of tissue damage incurred by microinfarcts is a miniscule percentage of total brain volume, we hypothesized that microinfarcts disrupt

The light microscope is traditionally an instrument of substantial size and expense. Its miniaturized integration would enable many new applications based on mass-producible, tiny microscopes. Key prospective usages include brain imaging in behaving animals for relating cellular dynamics to animal

We investigated cognitive function, axonal/white matter (WM) changes and glymphatic function of vascular dementia using a multiple microinfarction (MMI) model in retired breeder (RB) rats. The MMI model induces significant (p < 0.05) cognitive decline that worsens with age starting

Motile subpopulations in microbial communities are believed to be important for dispersal, quest for food, and material transport. Here, we show that motile cells in sessile colonies of peritrichously flagellated bacteria can self-organize into two adjacent, centimeter-scale motile rings surrounding

Although anti-angiogenic (AA) therapy is widely used in clinical practice, it is often challenged by insufficient efficacy and intrinsic resistance. Some studies have reported that AA therapy can even increase tumor metastasis. However, whether this is due to a specific
