Chemical Properties
| Description | DOTA-NHS-ester is a linker for affibody molecules with applications in small animal PET, SPECT, and CT. It can be used to label radiotherapeutic agents or imaging probes for tumor detection. |
| In vitro | METHODS: The binding kinetics of hIMB1636 to Trop2 antigen were measured by biofilm interferometry (BLI). Western blotting was used to screen Trop2 expression in pancreatic cancer cell lines. Flow cytometry and cell immunofluorescence were used to evaluate the binding ability of hIMB1636 and Trop2 on the cell surface. hIMB1636 was conjugated with p-SCN-Bn-NOTA (NOTA) and DOTA-NHS-ester (DOTA) for 64Cu and 177Lu radiolabeling. RESULTS According to the BLI results, hIMB1636 had a strong binding affinity to Trop2. According to the results of Western blotting, flow cytometry, and cell immunofluorescence, the T3M-4 cell line showed the strongest expression of Trop2 and the specific binding ability of hIMB1636. The radiochemical purity of 64Cu-NOTA-hIMB1636 and 177Lu-DOTA-hIMB1636 exceeded 95%. [2] |

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:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
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 DMSO (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.
(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 DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
