Texas Red (Synonyms: 磺基羅丹明 101; Sulforhodamine 101; SR101)

Texas Red (Sulforhodamine 101) 是一種兩性羅丹明紅色熒光染料 (excitation/emission: 586/605 nm)。Texas Red 被廣用于研究神經元形態(tài)，并作為星形膠質細胞的細胞類型選擇性熒光標記物，在體內和切片制備中都有應用。

生物活性

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 a cell type-selective fluorescent marker of astrocytes both in vivo and in slice preparations^[1].

體外研究(In Vitro)

Texas Red (Sulforhodamine 101) does not label astrocytes in brainstem slices as strong and specific as in the hippocampus or cortex. To minimize excitatory side effects, the concentration of Texas Red has to be kept as low as possible or the labeling procedure can be performed after the actual experiment^[1].

體內研究(In Vivo)

In vivo, epileptic activity can be induced by intra-hippocampal injection of small volumes of 10 μM Texas Red or topical application of 100 μM^[1].
