Alias Ac-Lys-Pro-N-Me-Arg-Arg-Pro-Tyr-Tle-Leu-OH

68Ga-DOTA-NT-20.3 is an analogue of neurotensin (NTS) and acts as a ligand for 68Ga ions. In PET imaging, it demonstrates rapid tumor uptake and high contrast between tumor and background, along with fast clearance from the blood and moderate accumulation in the kidneys. Its pharmacokinetic and biodistribution properties are advantageous, producing high-quality PET images in mice with subcutaneous or orthotopic human pancreatic cancer xenografts. 68Ga-DOTA-NT-20.3 specifically binds to NTSR1 on pancreatic cancer cells and outperforms 18F-FDG in PET detection of adenocarcinoma.

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:
TargetMol | Animal experiments For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent 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 DMSOTargetMol | reagent 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 DMSOTargetMol | reagent stock solution to 400 μL PEG300TargetMol | reagent 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 ddH2OTargetMol | reagent 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.
All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
