WebFluorescence spectra and quantum yields are generally more dependent on the environment than absorption spectra and extinction coefficients. For example, coupling a single fluorescein label to a protein typically … WebAnnexin V-FITC/PI 双染法细胞凋亡检测试剂盒 ， 简单有效 ！. 碘化丙啶 (Propidium Iodide, PI) 是一种核酸染料，它不能透过完整的细胞膜，但 PI 可以透过凋亡中晚期的细胞和死细胞的细胞膜，而使细胞核染上红色染料。 所以， Annexin V 和 PI 匹配使用，可以将处于不同凋亡时期的细胞区分开。

Extinction Coefficient [FITC (Fluorescein-5-isothiocyanate)]

WebThe molar extinction coefficient (ε) for Fluorescein is 80000 cm-1 M-1 in 0.1N NaOH. To request additional information and datasets for Fluorescein, please contact [email protected]. Unless otherwise specified, molar extinction coefficient (ε) values are typically measured in ddH 2 O or PBS.

Fluorescein, Oregon Green and Rhodamine Green Dyes—Section 1.5

WebMeasure the absorbance of the fluorophore at the wavelength of maximal excitation (e.g. for FITC use 495 nm wavelength). Divide this value by the molar extinction coefficient for the dye. ( e.g. FITC has an extinction coefficient of 75,000 M-1 cm-1). Determine the labeling. Divide the fluorophore concentration, determined in step 2, by the ... WebExtinction Coefficient: EmM = 39.8 (238 nm), 10.0 (284 nm) (0.01 M NaOH) Fluroescence properties: Excitation wavelength: 460 nm2 Emission wavelength: 515 nm2 Synonym: … WebSpectral characteristics of 6-Fam are identical to those of FITC (Fluorescein-5,6-isothiocyanate), which consists of a reactive species of fluorescein bearing an isothiocyanate reactive group. 6-Fam can be successfully used with most fluorescent detection devices available in the market. ...
