Bismuth 213 half life
WebApr 21, 2024 · The α-emitting radionuclide bismuth-213 (213 Bi) has interesting properties and can be considered as a magic bullet for TRNT. The benefits and drawbacks of targeted alpha therapy with 213 Bi are discussed in this review, covering the entire chain from radionuclide production to bedside. WebThe 0.3 microCi dose of (213)Bi on both the C6.5K-A and NM3E2 scFvs resulted in similar anti-tumor effects (p = 0.46) indicating that antigen-specific targeting was not a factor. This suggests that the physical half-life of (213)Bi may be too brief to be effectively paired with systemically-administered diabody or scFv molecules.
