Small Organic
~2.5 nM (reported value)
Buffer for CD binding assay: 10 mM sodium phosphate buffer (pH 7.5) and 100 mM NaCl.
4°C
Heated to 95°C and cooled to 4°C for over 2h.
The aptamer's affinity for argininamide and agmatine is 20-fold more than for arginine. Affinities for D-arginine, guanidine, and ethylguanidine are about the same.
