Texas Red

Texas Red (Sulforhodamine 101) is an amphoteric rhodamine red fluorescent dye (excitation/emission: 586/605 nm) . Texas Red is used extensively for investigating neuronal morphology and acts as acell type-selective fluorescent marker of astrocytes bothin vivoand in slice preparations[1].
