ADEL-Y01 is a humanized and parental murine blood-brain barrier-penetrating monoclonal antibody against tau-acK280. ADEL-Y01 specifically recognizes tau-acK280 and its surrounding residues, mediates the neutralization and phagocytosis of acetylated tau aggregates, and interferes with the activity of pathological tau protein. ADEL-Y01 prevents the progression of tauopathies, increases neuronal survival rate, reduces tau-related pathological changes, and improves memory impairment. ADEL-Y01 can be used in research related to Alzheimer's disease and tauopathies.

ADEL-Y01 (1.9 mg/mL; i.c.v.; continuous infusion; 28 days) ameliorates cognitive and pathological impairments in TauP301L-transgenic mice by reducing insoluble and modified tau levels[2].
ADEL-Y01 (50 mg/kg; i.p.; weekly; 3 months) ameliorates behavioral deficits and pathological tau changes in Tau-P301L-transgenic mice, with antibody crossing the blood-brain barrier to target tau-acK280[2].
ADEL-Y01 (50 mg/kg; i.p.; weekly; 3 months) improves cognitive performance and reduces tau aggregates in Tau-P301S-transgenic mice[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
