SULFORHODAMINE 101 Usage And Synthesis

Description

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 a long-lasting increase in evoked excitatory postsynaptic potentials in CA1 pyramidal neurons in hippocampal slices.

Chemical Properties

green to dark green crystalline powder

Uses

A red-emitting flurophore used to label astrocytes.

Uses

Sulforhodamine 101 is a red fluorescent dye used in the calcium imaging methods in neurophysiological experiments.Dyes and metabolites.

storage
