Sulforhodamine 101 is a nonfixable red fluorescent dye (excitation max: 586 nm, emission max: 605 nm) that can be used as a specific marker for astrocytes and an activity-dependent probe for monitoring regulated exocytosis. It has been reported to induce long-term potentiation of intrinsic neuronal excitability and...

Green crystalline. Soluble in water, methanol (1 mg/ml), ethanol, DMSO or DMF. 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...

Sulforhodamine 101 is a fluorescence reference standard for measuring fluorescence quantum yield. It is also the key precursor used for preparing rhodamine 101 sulfonyl chloride (also called Texas Red(R), a trademark of Molecular Probes).
