0.06 mM (reported value)
100 mM LiCl, 5 mM MgCl2, and 20 mM HEPES acid with pH adjusted to 7.4 using LiOH
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.
Binds to potassium preferentially over lithium, sodium, and other monovalent ions
Forms G-quadruplexes
