Summary
Aptamers are short DNA or RNA molecules that bind targets like proteins with high specificity. Aptamer technology, including SELEX, enables diverse applications in therapy and diagnostics.
Area of Science:
- Molecular Biology
- Biochemistry
Context:
- Aptamers are short nucleic acid sequences selected for target binding.
- They offer high specificity and affinity comparable to antibodies.
- Aptamers can also inhibit target molecule function.
Purpose:
- To discuss aptamer selection principles (SELEX technology).
- To explore the structural basis of aptamer-ligand interactions.
- To review diverse aptamer applications.
Summary:
- Aptamers bind targets with antibody-like specificity and affinity.
- SELEX technology is used for aptamer selection.
- Applications span diagnostics, therapeutics, and research tools.
Impact:
- Aptamers are valuable tools for biological research.
- Approved aptamer therapies exist for diseases like macular degeneration.
- Ongoing development for novel therapeutic and diagnostic uses.
