| Description | Posdinemab (JNJ-63733657) is a humanized monoclonal antibody targeting pT217 phosphorylated Tau. By specifically binding to pathological Tau, it blocks its propagation and aggregation between neurons, thereby delaying the progression of Alzheimer's and other tauopathies. |
| In vitro | In experiments using artificial cerebrospinal fluid and mouse brain homogenates, immunoprecipitation with 100 nM Posdinemab followed by 20 hours of enzymatic digestion, and subsequent analysis by LC-MS, demonstrated that it specifically enriches the diphosphorylated Tau peptide (SRTPSLPTPPTREPK2p) containing the pT217 site, confirming that this antibody exhibits extremely high affinity and precise selective capture capacity for pathologically phosphorylated tau protein [2]. |
