RhD antigen‑specificity 2 (ID# 8106)

Aptamer Chemistry: DNA

Target: RhD+ red blood cells

Antigen/Target Category: Cells

Affinity (Kd): 737.7±161.8 nM (reported value)

Binding Conditions/Buffer: 10 mM Tris-HCl, 50 mM KCl, pH 9.0), 1.5 mM MgCl2, 400 µM each dNTP, 2.5 U Taq DNA polymerase (Promega Corporation), and 50 pmol each biotinylated primer

Binding Temp: 25°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.
