How are aptamers made
Weban example in which two aptamers worked back to back in a co-operative fashion in a riboswitch. Both aptamers bound glycine, and the binding of glycine at one aptamer improved the binding affinity for the amino acid at the second aptamer (9). Breaker says, “It’s like hemoglobin, but only made of RNA.” The discovery of these in vivo ap- WebAffimers are recombinant proteins. As they are manufactured using recombinant bacterial production processes, the batch-to-batch consistency for Affimers is …
