2-NBDG is a fluorescently-labeled deoxyglucose analog that is used primarily to directly monitor glucose uptake by living cells and tissues. It is also used as a topical contrast reagent for the detection of neoplasia. 2-NBDG can be used in real-time confocal, high-resolution, or wide-field fluorescence microscopy as well as in flow cytometry. The probe can be excited by the Argon laser at 488 nm to give the environment-sensitive fluorescence. It has lower photostability than the rhodamine-based fluorescent probes. Storage: protect from light.

1. 2-NBDG 工作液准备
1.1 制备储存液
用 2.92 mL DDH₂O 稀释 1 mg 2-NBDG 配制 1 mM 储备液。
1.2 工作液的配制
用预热好的无血清细胞培养基或 PBS 稀释储存液，配制成 10-200 μM 的 2-NBDG 工作液。
注：请根据实际情况调整 2-NBDG 工作液浓度，且现用现配。

2.细胞染色
2.1 悬浮细胞：离心收集细胞，加入 PBS 洗涤两次，每次 5 分钟。
贴壁细胞：弃去培养基，加入胰蛋白酶消化细胞。离心弃去上清后，加入 PBS 洗涤两次，每次 5 分钟。
2.2 加入 1 mL 2-NBDG 工作液，室温孵育 5-60 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，使用显微镜进行观察，如果进行活力测试，使用 ELISA 酶标仪记录 540/570 nm 的光密度 (O.D.)。细胞活力以对照比计算，并与药物对数浓度绘制曲线，计算 IC₅₀。
