Biological Activity
DSPE-PEG-Amine (MW 2000) (ammonium) is coated on the surface of the fluorescein diacetate (FDA) nanocrystals to provide a interface for the antibody coupling. The DSPE-PEG-Amine (MW 2000) (ammonium)-modified biolabels have a highly stable colloidal suspension with minimized nonspecific interactions. The adsorbed DSPE-PEG-Amine (MW 2000) (ammonium) layer causes the FDA nanocrystals to disperse in water and prevents their aggregation, hence conferring colloidal stability[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
Ethanol : 16.67 mg/mL (Need ultrasonic)
DMSO : 7.14 mg/mL (ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.67 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (16.7 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
