STX M30f Aptamer

This part is an Aptamer for Saxitoxin (related to the red tide), this aptamer was developed by Zheng et. al. 2015, and it was selected by a pool of aptamers developed in the same research, this aptamer has a dissociation constant (Kd) of of 0.133 µM. You can see the structure in the absence of the toxin in Figure 1, the conformation of the molecule in the presence of the toxin is still unknown.
