M5 (ID# 9590)

Aptamer Chemistry: DNA

Target: Mutant Q78 Huntingtin

Antigen/Target Category: Protein

Affinity (Kd): N/A nM (reported value)

Binding Conditions/Buffer: Binding conditions were evaluated with a typical ELISA. Binding depletion type of ELISA was conducted to evaluate aptamer binding efficiency.

Binding Temp: 25°C

Refolding Protocol: N/A

Specificity: Upon digestion of biotinylated aptamer-mutant huntingtin complex with caspase 6, the aptamer specifically bound to the C terminal region of the protein. Aptamer specific to Q78 huntingtin, not Q23 huntingtin.

Comments: Among the four aptamers tested, MS3 interacted better with Q78 huntingtin and selectively reduced its PRC2 stimulating activity.
