WebDextran is essentially a linear glucose chain linked by α-D-(1 – 6) linkages. The degree of branching is about 5 %. The fluorescein moiety is attached by a stable thiocarbamoyl linkage and the labelling procedure does not lead to any depolymerization of the dextran. FITC-dextrans have from 0.001-0.020 mol FITC per glucose unit. WebFITC-Dextran (MW 4000) 是一种异硫氰酸荧光素 (FITC) 葡聚糖荧光探针 (Ex=495 nm; Em=525 nm)。FITC-Dextran (MW 4000) 可作为一种标记物来揭示热休克引起的细胞损伤,并研究细胞凋亡的早期和晚期阶段。FITC-Dextran (MW 4000) 还可用于细胞渗透性的研究,如血脑屏障通透性以及血脑屏障破坏程度的测定。
