DOTA-LM3 TFA

Catalog No. T78110

DOTA-LM3 TFA is a somatostatin receptor (SSTR) antagonist with the molecular structure p-Cl-Phe-cyclo(D-Cys-Tyr-D-4-amino-Phe(carbamoyl)-Lys-Thr-Cys)D-Tyr-NH2, used for in vivo tumor tracing via isotopic labeling, such as 177Lu-DOTA-LM3 TFA and 68Ga-DOTA-LM3 TFA. The 68Ga-labeled compound shows favorable biodistribution, high tumor uptake, good tumor retention, and minimal safety concerns, while the 177Lu-labeled variant targets DOTATOC-negative liver metastases, including pancreatic NET and extensive tumor thrombosis [1] [2].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
