[Abstract]; Representative immunofluorescence images showing that mCherry-PCBP2 condensates (red) do not substantially colocalize with the Thioflavin S (ThioS; 0.1% w/v) in SH-SY5Y-mCherry-PCBP2 cells. Arrows in green: amyloid plaques or aggresome, red: PCBP2 condensates.

: Thioflavine S purchased from MedChemExpress. Usage Cited in: Basic Res Cardiol. 2021 Dec 16;116(1):65. [Abstract]; Thioflavin S (1 mL/kg; Tail vein injection). Endothelial-specific overexpression of HINT2 protected the cardiac microcirculation against I/R injury by modulating the MCU complex. Mice were transfected with AAV9-NC or AAV9-HINT2 and suffered from 45 min ischemia and 6 h reperfusion injury. Ru360 was injected intraperitoneally into AAV9-NC mice 1 h before I/R injury to inhibit the MCU complex. Spermine was injected intraperitoneally into AAV9-HINT2 mice 1 h before I/R injury to activate the MCU complex. No reflow area after reperfusion was detected by Thioflavin S staining and quantified.

製品説明	Thioflavine S is a fluorescent histochemical marker of dense core senile plaques. Thioflavine S can be used for Alzheimer's research^[1].
体外実験	Guidelines (The following is our recommended experimental protocol. This protocol is for reference only, and specific operations should be adjusted according to your actual needs). Thioflavine S staining protocol 1.Deparaffinization and hydration of tissue sections: Place slides in holders and treat with the clearing agent xylene (paraffin solvent) and a series of graded EtOH as follows: 100% xylene - 5 min 100% xylene - 5 min 50%/50% xylene/100% EtOH - 3 min 100% EtOH - 3 min 95% EtOH - 3 min 70% EtOH - 3 min 50% EtOH - 3 min Water - 2 x 3 min Note: Change the solns after about 5 uses or when you see the soln is not cleanly running off the slides, indicating too much paraffin in them. 2.Incubate in filtered 1% aqueous Thioflavine-S for 8 minutes at room temperature (filter Thioflavin-S before each use). Note: protect thioflavin-S from light, and protect the stained slides from light as much as possible. Thioflavin-S stain should be stored at 4°C. 3.Wash 2x 3 min in 80% ethanol 4.Wash 3 min in 95% ethanol 5.Wash with 3 exchanges of distilled water 6.Coverslip in aqueous mounting media and allow slides to dry in the dark overnight. 7.Next day, seal coverslip with clear nail polish. 8.Analyze slides within the next few days-weeks because the staining will fade with time. Store the slides in the dark at 4°C. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Thioflavine S 関連抗体

Dyeing Example	Description: Thioflavine S (Thioflavin S) is a fluorescent histochemical marker with green fluorescence, it can be used to measure the myocardial no-refow phenomenon. Method: For Thioflavine S staining assay. 1. Thioflavine S (1 mL/kg, 6%) is injected into mice via the tail vein and allowed to circulate for 1-2 min. 2. The hearts are quickly harvested, fixed in 4% paraformaldehyde (PFA) overnight, cut into 1 mm sections, and then observed under a stereomicroscope (Leica, Germany). Description: Thioflavine S (Thioflavin S) is a fluorescent histochemical marker with green fluorescence, it can be used to measure the extracellular insoluble Aβ plaque deposits in the whole brain of mice. Method: For brain tissue staining. 1. Wash mouse brain tissues for three times in PBS (5 min). 2. Stain sliced brain tissues with Thioflavine S (500 µM; 8 min; room temperature) solution dissolved in 50% ethanol. 3. Subsequently, after incubating the tissues twice in 50% ethanol for 3 min, the tissues are washed with PBS for 5 min. 4. Brain tissue sections are mounted on glass slides using a TissueFAXS plus (TissueGnostics GmbH, Vienna, Austria) and using a Zeiss Axio Imager Z2 Microscope System (Carl Zeiss, Jena, Germany) for image. Description: Thioflavine S (Thioflavin S) is a fluorescent histochemical marker with green fluorescence, it can be used to evaluate amyloid deposition. Method: For brain tissue staining. 1. Testing sections are immersed in Thioflavine S (1%; 5 min), hydrated in 70% ethanol and washed for 5 min with PBS for twice. 2. The sections are sealed with a fluorescent mounting media. Pannoramic MIDI is used to scan the images and analyze the data. Description: Thioflavine S (Thioflavin S) is a fluorescent histochemical marker with green fluorescence, it can be used to measure the aggregation of α-syn. Method: For brain sections staining. 1. Stain sections with Thioflavine S solution (10 mg/mL; 5 min). 2. Wash cells for twice. 3. The sections are mounted on slides and images are gathered using a fluorescence microscope (Olympus). Description: Thioflavine S (Thioflavin S) is a fluorescent histochemical marker, it can be used to monitor the accumulation of Aβ. Method: For cell staining. 1. Inoculate cells on a 24-well culture plate and fix cells with 4% paraformaldehyde (15 min; 25℃). 2. Add 80% ethanol to percolate at -20℃ for 6 min. 3. Add Thioflavine S (0.1%; 5 min; 25℃) to percolate for incubate cells. 4. Use the ImageXpress High-content Imaging system for image. Image Pro Plus 6.0 Image analysis software is used to detect the average fluorescence density.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
