| Description | EC-17 (disodium salt), a folate receptor alpha (FRα) targeting contrast agent, exhibits fluorescent properties within the visible light spectrum, characterized by peak excitation and emission wavelengths of 470/520 nm, respectively. |
| 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. 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. |
| In vivo | Fluorescence microscopy utilizing folate-FITC demonstrated a pronounced signal across all malignant tumors possessing FR-α, indicating a significant expression. In contrast, no signal was detected in malignant or benign lesions lacking FR-α. Furthermore, the average fluorescence intensity measured in animals administered with EC-17 was 42,234 ± 12,234 arbitrary units (au), underscoring the specificity of the response. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
