2-Aminoethyl-mono-amide-DOTA-tris(tBu ester)
Based on 1 Customer Validation
2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) is a metal chelator precursor containing a DOTA macrocyclic structure. DOTA can form highly stable complexes with metal ions (such as 68Ga, 177Lu) through four nitrogen atoms and four carboxylic acid groups to mediate targeted delivery of radionuclides. The tert-butyl ester group (tBu ester) of 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) also protects the carboxylic acid group during synthesis, and forms a free carboxyl group after deprotection reaction for coupling with targeting molecules (such as antibodies, peptides). 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) may be combined with tumor pre-targeting systems through bioorthogonal reactions (such as reverse electron demand Diels-Alder reaction) to study radioactive imaging or therapy of tumor tissues, and is mainly used in tumor pre-targeting research in the field of nuclear medicine.

In Vivo:
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% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.07 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.07 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
