Aptagen, LLCRNA L-Arginine Small Organic 330 nM (reported value) Binding buffer: 250 mM NaCl, 50 mM Trisƒ??HCl (pH 7.6), 5 mM MgCl2 NA If the oligo is a known aptamer sequence: For binding studies, perform a refolding program 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.
