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.
ssDNA aptamers specific for SEA were selected using a 12-round SELEX procedure. A15 was used successfully in fluorescent bioassay to detect SEA in the food sample with a detection limit of 8.7 x 10^(-3) ug/mL.
