Ion-OspA-59 (ID# 8239)

Outer Surface Protein A (OspA)
2.18 nM (reported value)
The SERS substrate surface was incubated with 10uM thiolated aptamers in low salt buffer (LSB*) including 1mg/mL PEG2000 and 1mg/mL PEG2-Azide for 12 hours at 4°C at 100% humidity. *LSB is composed of 48mM NaCl, 1mM KCl, 42 mM Na phosphate, and 5mM MgCl2 with a pH of 7.4. This was at 23°C.
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.

Note: Information on this aptamer oligo was obtained from the literature and hasn't been validated by Aptagen.
