| Description | Dihydrorhodamine 123 (DHR 123) is a fluorescent probe (λex=488 nm, λem=525 nm). |
| In vitro | 在10 μM Dihydrorhodamine 123 (DHR 123)存在下，通过加入50 nM phorbol 12-myristate 13-acetate (PMA)刺激中性粒细胞NADPH氧化酶会导致rhodamine生成速率的增加。同时，在10 μM Dihydrorhodamine 123存在的条件下，经PMA（50 nM）刺激的HL60细胞表现出持续的荧光增强。 |
