Affinity  Techniques and Our Survey

Life is all about specific recognition and affinity binding. Such biological recognition processes include antigen/antibody recognition, hormone/receptor binding, enzyme/substrate, protein-protein, protein-DNA and cell-cell interactions, and the various interactions involved in nucleic acid transcription. Nature has evolved many mechanisms and structures able to discriminate minor changes in chemical structures to achieve these highly specific processes through various interactions, for instance hydrogen bonding, ionic, van der Waals or hydrophobic interactions etc.
