Medchemexpress LLC Thioflavin T | 2390-54-7 | 99.4% | 500 MG

Thioflavin T is a cationic Benzothiazole dye that exhibits enhanced fluorescence upon binding to amyloid in tissue sections. It is a fluorescent dye used for staining Aβ fibrils with green fluorescence and is commonly used to measure protein fibrillation. Weakly fluorescent in aqueous solutions, it shows enhanced emission at 482 nm when bound to Aβ plaques. It can be applied in Alzheimer's disease research and to detect endoplasmic reticulum stress (ERS) by displaying green fluorescence when binding to protein aggregates.

Enzo Life Sciences MQAE (ultra pure) (100mg). CAS: 162558-52-3

MQAE is a fluorescent chloride ion indicator that is more sensitive and selective than 36Cl and microelectrode-based methods for chloride measurement in cells. MQAE is a fluorescent indicator that is quenched via collision with chloride. The probe is suitable for detection of chloride concentrations in liposomes, reconstituted membranes or in extracellular medium. As a UV-excitable indicator, MEQ can be detected using an argon-ion laser for confocal microscopy and flow cytometry applications. MQAE has greater sensitivity than SPQ and higher fluorescence quantum yield. The ester group of MQAE may slowly hydrolyze inside cells, resulting in a change in its fluorescence response. Wavelength Maxima: Excitation 350nm, Emission 460nm Alternative name: N-(Ethoxycarbonylmethyl)-6-methoxyquinolinium bromide. Purity: ≥98% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
