The Emission of Internal Conversion Electrons Rather Than Auger Electrons Increased the Nucleus-Absorbed Dose for 161Tb Compared with 177Lu with a Higher Dose Response for [161Tb]Tb-DOTA-LM3 Than for [161Tb]Tb-DOTATATE. [Abstract]2024 Oct 1;65(10):1619-1625. PMID: 39209546
DOTATATE purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625. [Abstract]
Total absorbed dose to cell nucleus for range of added activity concentrations of both 161Tb- and 177Lu-labeled DOTATATE (0-1.25 MBq/mL).
DOTATATE purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625. [Abstract]
Radiolabeled DOTATATE (1 MBq/mL) resulted in a higher absorbed dose than did radiolabeled DOTA-LM3, because of DOTATATE's higher Bmax and higher internalization.
DOTATATE purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625. [Abstract]
The nuclear dose-response data of both [177Lu]Lu- and [161Tb]Tb-DOTATATE (0-25 Gy) were best fitted with a linear model and could be fitted with a common, single curve.
DOTATATE purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625. [Abstract]
The saturation binding assay represented total binding and nonspecific binding for different added activity concentrations of [161Tb]Tb-DOTATATE (0-60 nM) with a fixed molar activity of 100 MBq/nmol.
DOTATATE purchased from MedChemExpress. Usage Cited in: J Nucl Med. 2024 Oct 1;65(10):1619-1625. [Abstract]
Clonogenic survival of CA20948 cells after treatment with [161Tb]Tb- and [177Lu]Lu-DOTATATE (0-1.5 MBq/mL) as a function of added activity concentration (MBq/mL).
