生物活性

Sulforhodamine 101 (SR101) is an amphoteric rhodamine red fluorescent dye (excitation/emission: 586/605 nm). Sulforhodamine 101 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].

体外研究
(In Vitro)

Sulforhodamine 101 (SR101) 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 Sulforhodamine 101 has to be kept as low as possible or the labeling procedure can be performed after the actual experiment[1].

体内研究
(In Vivo)

In vivo, epileptic activity can be induced by intra-hippocampal injection of small volumes of 10 μM Sulforhodamine 101 or topical application of 100 μM[1].

Cell Assay
[1]

Acute brain slices are usually incubated in carbonated extracellular solution containing 0.5 to1 μM Sulforhodamine 101 for 20 to 30 min and 34 to 37°C. Following this, excess dye is removed over a period of 10 to 30 min using different protocols that were described earlier[1].

Animal Administration
[1]

For in vivo imaging, Sulforhodamine 101 (SR101) is applied topically at concentrations of 250 nM to 300 μM or by bolus injection. Additionally, Sulforhodamine 101 injection over the tail vein (10 mg/mL) has been reported to be successful[1].

生物活性

Sulforhodamine B sodium salt is a fluorescent dye with uses spanning from laser-induced fluorescence (LIF) to the quantification of cellular proteins of cultured cells.

体外研究
(In Vitro)

Sulforhodamine B (SRB) is often used as a membrane-impermeable polar tracer or used for cell density determination via determination of cellular proteins (cytotoxicity assay). The SRB assay has been used to inexpensively conduct various screening assays to investigate cytotoxicity in cell based studies. This method relies on the property of SRB, which binds stoichiometrically to proteins under mild acidic conditions and then can be extracted using basic conditions; thus, the amount of bound dye can be used as a proxy for cell mass, which can then be extrapolated to measure cell proliferation. The protocol can be divided into four main steps: preparation of treatment, incubation of cells with treatment of choice, cell fixation and SRB staining, and absorbance measurement. This assay is limited to manual or semiautomatic screening, and can be used in an efficient and sensitive manner to test chemotherapeutic drugs or small molecules in adherent cells. It also has applications in evaluating the effects of gene expression modulation (knockdown, gene expression upregulation), as well as to study the effects of miRNA replacement on cell proliferation[1].

Cell Assay
[1]

Gently add 25 μL (96-well format) or 5 μL (384-well format) cold 50% (wt/vol) TCA to each well directly to medium supernatant, and incubate the plates at 4 °C for 1 h. Mixing is not required, as this could lead to some cells detaching from the bottom of the well. Wash the plates four times by submerging the plate in a tub with slow-running tap water and remove excess water by gently tapping the plate into a paper towel. After the last wash allow the plate to air-dry at room temperature. Add 50 μL (96-well format) or 20 μL (384-well format) of 0.04% (wt/vol) SRB solution to each well. Leave at room temperature for 1 h and then quickly rinse the plates four times with 1% (vol/vol) acetic acid (200 μL for 96-well format or 30 μL for 384-well format) to remove unbound dye. Allow the plate to air-dry at room temperature[1].
