Apple Stem Pitting Virus of PSAH PearIsolate (ID# 7561)

Aptamer Chemistry: DNA

Target: Apple Stem Pitting Virus (ASPV)

Antigen/Target Category: Protein

Affinity (Kd): 8 nM (reported value)

Binding Conditions/Buffer: Selection Buffer: PBS-T (10 mM Na₂HPO₄, 2 mM KH₂PO₄, 2.7 mM KCl, 137 mM NaCl, and 0.05%Triton-X; pH 7.5) with added 0.1 μg/ml poly-dIdC and 1 μg/ml BSA.

Binding Temp: RT°C

Refolding Protocol: NA If the oligo is a known aptamer sequence: For binding studies, perform a refolding protocol to ensure proper function (i.e. binding to antigen or target). Refer to the aptamer reference source for the appropriate refolding parameters and binding conditions. Note: it is unknown whether aptamer functions properly without refolding.

Specificity: Binds to the MT32 coat protein with reduced affinity (290 nM).
