FITC-Dextran (MW 110000) 

FITC-Dextran (MW 110000) is a compound belonging to the class of fluorescent dyes. It is commonly used in biomedical research as a tracer molecule to label and track cells or other biological matter. FITC-Dextran consists of fluorescein isothiocyanate (FITC) and dextran, a complex carbohydrate derived from starch. The combination of the two creates a stable fluorescent tracer that can be viewed under a microscope or quantified using specialized detection instruments.

FITC-Dextran (MW 110000) 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 110000) 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 110000) 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。储存方式：避光。
