What Are Aptamers?


Aptamers (synthetic antibodies) are stable DNA or RNA ligands that bind with high affinity and specificity to target antigens such as small molecules, peptides, proteins, cells, and tissues. For example, aptamers have been generated that exhibit greater than 10,000-fold binding affinity for theophylline over caffeine, which differ only by a few atoms.
Aptamer products can be used as research agents, diagnostics, biosensors, and tools for biomarker or drug discovery. Aptamers can also be used for bioindustrial applications and targeted therapeutics.

Antibody problems? Have difficult targets to develop effective ligands or antibodies? What if an antibody doesn’t exist for your target or antigen? 
No problem. Let Aptagen provide you with an alternative – the aptamer. You’ve heard about this new technology. Now, try it.

What is an aptamer?

Aptamers (synthetic antibodies) are (stable) single-stranded DNA, RNA, or peptide molecules capable of binding to its target antigen with high affinity and specificity. Aptamers (synthetic antibodies) have been developed against a wide variety of targets ranging from small organics to large proteins.


  • Manufacturing costs and time are all lower compared to that of monoclonal antibody production.
  • Once the aptamer (nucleic acid) sequence is known, the aptamer (synthetic antibody) can be produced on the fly using an oligo synthesizer to meet ones immediate needs.
  • Easy to label with reporters, enzymes, or fluorescent tags.
