产品详情
DiD 是一种长链碳菁染料。碳菁染料广泛用作亲脂性示踪剂,用于标记细胞、细胞器、脂质体、病毒和脂蛋白。
生物活性
DiD is a long-chain carbocyanine dye. Carbocyanine dyes are widely used as Di to label cells, organelles, liposomes, viruses and lipoproteins.
性状
Solid
体外研究(In Vitro)
制备 Di 染色溶液1.1 制备 DMF、DMSO 或乙醇储备溶液:储备溶液应在 1-5 mM 的二甲基甲酰胺 (DMF) 、二甲基亚砜 (DMSO 或乙醇 DMSO 中制备。DMF 比乙醇更适合作为 Di 的溶剂。储备溶液应及时使用。任何未使用的溶液可作分装储存在 -20℃。避免反复冻融,溶液可储存 6 个月。1.2 制备工作溶液:将储备溶液稀释到合适的缓冲液中,如无血清培养基、HBS 或 PBS,以制备 1-5 μM工作溶液,现配现用。注:应根据经验确定不同实验条件下工作溶液的最终浓度。2. 悬浮细胞2.1 悬浮细胞:离心收集细胞,加入 PBS 洗涤两次,每次 5 分钟。细胞密度在 1×10/mL2.2 加入 1 mL Di 工作液,室温孵育 5-30 分钟。2.3 400 g,4℃ 离心 3-4 分钟,弃去上清。2.4 加入 PBS 洗涤细胞两次,每次 5 分钟。2.5 用 1 mL 无血清培养基或 PBS 重悬细胞后,使用荧光显微镜或流式细胞仪进行观察。3. 贴壁细胞3.1 将贴壁细胞培养于无菌盖玻片上。3.2 从培养基中移出盖玻片,吸除多余培养基。3.3 加入 100 μL 染料工作液,轻轻晃动使其完全覆盖细胞,孵育 5-30 分钟。3.4 吸去染料工作液,用培养基洗 2-3 次,每次 5 分钟,使用荧光显微镜或流式细胞仪进行观察。 has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Two weeks after injection of stained cells, a single, bright, DiD perchlorate (DiD)-positive cells located between 15 to 40 μm from the endosteum is found. Results reveal a progressive appearance of cell clusters of decreased dye intensity, consistent with the partitioning of DiD perchlorate label on cell division. has not independently confirmed the accuracy of these methods.
