| Notes |
Carbodiimide mediated blocking of free carboxylic acids (Asp/Glu sidechains and C-termini) with ethanolamine; reaction yields an amide-bond between the carboxylic acid of the peptide/protein and the primary amine of ethanolamine; reaction irreversibly modifies carboxylic acids. Shown above is the composition of the mass adduct, after substraction of water. |
