产品详情

EC-17 (disodium salt)是一种叶酸受体α (FRα) 的靶向造影剂，在可见光谱中具有荧光特性。 EC-17的激发和发射波长为470/520 nm。

生物活性

EC-17 (disodium salt) is a folate receptor alpha (FRα) targeting contrast agent with fluorescent properties in the visible light spectrum. The peak excitation and emission wavelengths of EC-17 are 470/520?nm.

Solid

IC50 & Target[1][2]

Folate receptor alpha

体外研究(In Vitro)

EC-17 contains the fluorescein fluorochrome and has a spectral wavelength of 490–530?nm. EC-17 is synthesized by a folate (vitamin B9) and fluorescein isothiocyanate (FITC) conjugated through an ethylenediamine spacer to produce folate-FITC, with a molecular weight of 917?kDa. FITC is a derivative of fluorescein functionalized with an isothiocyanate reactive group. The folate-FITC conjugate forms a negatively charged fluorescent molecule that specifically targets cell-surface FRα and is subsequently internalized into the cytoplasm. The signal-to-background ratio (SBR) of EC-17 for HeLa cells range from 0.97 to 7.32 depending on the molarity and concentration of cancer cells. has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

The mean fluorescence signal from the animals injected with EC-17 to be 42,234 ± 12,234?au. Fluorescence microscopy for folate-FITC shows a strong signal in all malignant tumors with FR-α expression and no signal in FR-α–negative malignant or benign lesions. has not independently confirmed the accuracy of these methods. They are for reference only.
