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 . </P>
