Sulforhodamine 101 (SR101) is a red fluorescent dye. In neurophysiological experiments which comprise calcium imaging methods, it can be used for a counterstaining of astrocytes to be able to analyze data from neurons separately. However, in addition to labeling astrocytes, SR101 labels myelinating oligodendrocytes. SR101 has been reported to affect excitability of neurons and should therefore be used with caution.
