EDC 与羧基反应,形成胺反应性O-酰基异脲中间体。如果这种中间体不遇到胺,它将水解并再生羧基。在存在N-羟基磺基琥珀酰亚胺(磺基-NHS)的情况下,EDC 可用于将羧基转换为胺反应性磺基-NHS 酯。这是通过将 EDC 与含有羧基的分子混合并添加磺基-NHS 来实现的。

Although NHS or Sulfo-NHS is not required for carbodiimide reactions, their use greatly enhances coupling efficiency. Furthermore, using NHS or Sulfo-NHS makes it possible to perform a two-step reaction. Both NHS and Sulfo-NHS are soluble in aqueous and organic solvents. Activation with NHS, ...
Procedure for Using EDC for Coupling Haptens to a Carrier Protein Materials Required • Carrier protein: 2 mg bovine serum albumin (BSA), ovalbumin (OVA) or keyhole limpet hemocyanin (KLH) • Conjugation Buffer: 0.1 M MES (2-[N -morpholino]ethane sulfonic acid), pH 4.5-5 (Product ...
so what else could be coupling to the nanoparticles? Does EDC degrade to form any amines capable of reacting with activated NHS ester? The EDC I used was ~4 years old so my first thought was that it may have degraded but I wanted to get your opinions first. Any advice appreciated!
2-mercaptoethanol, or the excess reagent can be simply removed (as well as the reaction pH adjusted) by buffer-exchange with a desalting column. Materials Required ? Activation Buffer: 0.1 M MES, 0.5 M NaCl, pH 6.0 ? Coupling Buffer: Phosphate-buffered saline (PBS), 100 mM sodium ...
