一般描述
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)键作为葡聚糖的分支。 天然葡聚糖的分子量(MW)经证实在 900 万至 5 亿的范围内。FITC-葡聚糖的最大激发波长为 490nm。它的 pH 范围为 5 至 9。
应用
异硫氰酸荧光素-葡聚糖(FITC-右旋糖酐,荧光素右旋糖酐,FITC)用于以下过程:
- 荧光素-葡聚糖显微镜。
- 评估多形核白细胞α防御素表达转基因小鼠体内肺血管的通透性。
- 通过流式细胞术定量细胞吞噬能力。
- 标记α乳白蛋白和脱氧核糖核酸酶。
用异硫氰酸荧光素标记的葡聚糖可用于动物的灌注研究。
制备说明
Sigma 通常以 25mg/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。 在体内,FITC-葡聚糖稳定超过 24 小时。
其他说明
与 FD-40 类似,但由 Sigma 生产。
天然葡聚糖的分子量(MW)经证实在 900 万至 5 亿的范围内。较低分子量的葡聚糖将表现出略微较少的分支,并且具有更窄的分子量分布范围。分子量大于 10,000 的葡聚糖则表现为高度支化。 随着分子量增加,葡聚糖分子的对称性增强。 分子量为 2,000 至 10,000 的葡聚糖表现出可膨胀线圈的特性。 在分子量低于 2,000 时,葡聚糖更像棒状。通过以下一种或多种方法测量葡聚糖的分子量:低角度激光散射、尺寸排阻色谱法、铜络合和蒽酮试剂显色还原末端糖测定和粘度。
