Binding sites of progesterone aptamer

WebAptamer–complementary DNA (cDNA) oligonucleotides were tested to maximize the signal gain of the aptasensor after binding with progesterone. Significant signal enhancement was observed when the aptamer hybridized with a short complementary sequence at specific site was used instead of pure aptamer. WebAug 15, 2024 · Aptamers provide several benefits, including the ease of labelling fluorophores on specific sites, binding-induced changes in aptamer structures, hybridization of the aptamers to complementary sequences, changes in molecular volume upon binding of the aptamer to its target, and adsorption of aptamers onto nanomaterials.
