Aptamers, which are nucleic acid ligands, offer promising cytokine detection. Systematic Evolution of Ligands by Exponential Enrichment (SELEX) generates these aptamers for various sensitive assay formats.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Analytical Chemistry

Background:

  • Aptamers are short nucleic acid ligands with high target affinity.
  • Cytokine detection is crucial in biological and medical research.
  • Existing detection methods have limitations.

Purpose of the Study:

  • To discuss the selection of aptamers using Systematic Evolution of Ligands by Exponential Enrichment (SELEX).
  • To review aptamer-based assay formats for cytokine detection.

Main Methods:

  • Systematic Evolution of Ligands by Exponential Enrichment (SELEX) for aptamer generation.
  • Description of various aptamer-based assay formats: ELISA, ALOA, fluorescence assays, and proximity ligation assays.

Main Results:
