New technologies in affinity assays to explore biological communication

  • Michael G. RoperEmail author

The language that cells use to communicate consists of the small molecules, peptides, and proteins that are released into the extracellular environment. To decipher this language, analytical assays are needed that have high selectivity, high sensitivity, and fast temporal resolution. Affinity assays are a group of analytical methodologies that are adept at studying this communication. In this overview, we highlight several examples from the literature on various types of affinity assays used in different platforms to monitor biological communication of peptides and proteins.
