NHS Esters

An NHS ester allows the functionalization of an amino moiety in a variety of molecules, including DNA and RNA oligonucleotides, as well as peptides or proteins.  NHS esters are especially useful in situations where the equivalent phosphoramidites exhibit instability to the conditions of oligonucleotide synthesis and/or deprotection.
