1-Ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride (EDC or EDAC) is a zero-length crosslinking agent used to couple carboxyl groups to primary amines. This crosslinker has been used in diverse applications such as forming amide bonds in peptide synthesis, attaching haptens to carrier proteins to form immunogens, labeling nucleic acids through 5' phosphate groups and creating amine-reactive NHS-esters of biomolecules. EDC reacts with a carboxyl to form an amine-reactive O-acylisourea intermediate. If this intermediate does not encounter an amine, it will hydrolyze and regenerate the carboxyl group. In the presence of N-hydroxysulfosuccinimide (Sulfo-NHS), EDC can be used to convert carboxyl groups to amine-reactive Sulfo-NHS esters. This is accomplished by mixing the EDC with a carboxyl containing molecule and adding Sulfo-NHS.


  • Several conjugation strategies—react EDC alone with target groups or include NHS or Sulfo-NHS to increase reaction efficiency or to stabilize active intermediate for later reaction to amines
  • Neutral linkage—forms neutral amide bonds between carboxyls and amines
  • Water-soluble reagent—add directly to reactions in aqueous, physiological buffers
  • Soluble reaction byproducts—easily removed by washing with water or dilute acid
