Xanthine (XAB) (ID# 7511)

Aptamer Chemistry: RNA

Target: Xanthine

Antigen/Target Category: Small Organic

Affinity (Kd): 3.3 nM (reported value)

Binding Conditions/Buffer: Binding Buffer (20 mM Trisƒ??HCl (pH 7.5), 0.3 M NaCl and 5 mM MgCl2)

Binding Temp: N/A°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.
