同义名:
钙黄绿素乙酰氧基甲酯
/ Calcein acetoxymethyl ester;NSC 689290
Calcein-AM是一种细胞可渗透化合物,进入细胞后无荧光。一旦进入细胞内,内源性酯酶将其水解为钙黄绿素,这是一种不能穿过细胞膜的极性分子,发出强烈的绿色荧光。它常与碘化丙啶一起用于细胞活力或细胞毒性测定,激发/发射波长为494/515 nm。

描述 | Calcein AM is permeable to cell membranes, allowing for easy entry into cells. Initially non-fluorescent, it is converted by cellular endogenous esterases into the polar molecule Calcein, which carries a strong negative charge and remains within the cell due to its inability to cross the cell membrane. Calcein emits intense green fluorescence, making it a popular choice for pairing with Propidium Iodide in assays to assess cell viability or virulence, with an excitation/emission wavelength of 494/515 nm[1]. |
体内研究 | Calcein-AM proves to be advantageous for in vivo studies due to its non-toxic nature to cellular functions and its efficacy as a marker of cell viability, highlighting its suitability for biological research[2]. |
