Description

General description

Sulforhodamine 101 is a red fluorescent dye. It is water-soluble, amphoteric rhodamine. The dye can be specifically used as a marker of astroglia in the neocortex. It is commonly used for brain imaging. Studies suggest that sulforhodamine 101 may be used as an epileptogenic agent.

Application

Sulforhodamine 101 acid chloride has been used in an encapsulated fluorescent probe as a model drug to study drug-delivery properties of rhamnogalacturonan-I based microcapsules. It has also been used in confocal imaging as an astrocyte specific dye.

Other Notes

Mixture of the two monosulfonyl chloride derivatives of sulforhodamine 101.
