AdipoGen Sulforhodamine 101, 60311-02-6, MFCD00012407, 500 mg
MF: C31H30N2O7S2, MW: 606.71, ≥99%, Appearance: Green crystalline. Sulforhodamine 101 is a non-fixable red fluorescent dye used as a specific marker for astrocytes and an activity-dependent probe for monitoring regulated exocytosis. In addition to labeling astrocytes, it also labels myelinating oligodendrocytes. Has been reported to affect excitability of neurons and should therefore be used with caution.
