Armanezumab
Armanezumab is a monoclonal antibody that targets and inhibits tau protein, and it specifically binds to the exposed N-terminal domain of pathological tau protein. Armanezumab can be used in relevant studies on Alzheimer's disease, frontotemporal dementia, and Pick's disease.

Biological Activity
Human
Armanezumab (3-243 nM) binds recombinant human 0N/4R tau protein with a high affinity, characterized by an equilibrium dissociation constant of 38.8 nM[1].
Armanezumab (0.02-12.5 μM; 1.5 h) specifically targets the PRQEF epitope (amino acids 4-8) of tau2-18, with amino acids 6 (glutamine) and 7 (glutamic acid) being essential for binding[1].
Armanezumab (1 μM; 16 h) partially protects SH-SY5Y human neuroblastoma cells from tau oligomer-mediated cytotoxicity[1].

-
Cell Line:SH-SY5Y human neuroblastoma cells
-
Concentration:1 μM (Armanezumab pre-incubated with 0.5 μM tau oligomers)
-
Incubation Time:16 h (cell incubation with oligomer-Armanezumab mixture)
-
Result:Restored SH-SY5Y cell viability to 89% compared to 36% viability in cells treated with tau oligomers alone, protecting cells from tau oligomer-mediated cytotoxicity.
