生物活性
Sulforhodamine 101 is a fluorescent dye (excitation maximum ~ 586 nm; emission maximum ~ 606). Selective astrocyte marker. Sulforhodamine 101 is used to determine morphological characteristics of astrocytes and to observe the association of astrocytes with the cortical microvasculature.
Furthermore, this fluorophore is used as an activity-dependent dye for monitoring regulated exocytosis. Alternate studies suggest that Sulforhodamine 101 can increase intrinsic neuronal excitability and long-lasting increases in evoked EPSCs in CA1 pyramidal neurons in hippocampal slices. Sulforhodamine 101 enhances evoked synaptic N-methyl D-aspartate receptor (NMDAR) currents which can be blocked by the antagonist, AP-5.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
