WebApr 7, 2024 · EDC/NHS coupling reaction is the most common: the carboxyl (COOH) group is converted in an active NHS ester able to form an amide bond with the primary amine from the ligand (Figure 3A) [45,46]. This strategy is usually used for MUA or dextran-covered surfaces because they already contain carboxyl groups.

WebThe NHS esters produced by EDC/NHS and EDC/sulfoNHS were proposed to be more stable than the O-acylisourea ester produced by EDC. The EDC/NHS or EDC/sulfoNHS based crosslinking was also specified to be optimal at pH 7.2–8.5. The isoelectric points (pI) of most IgGs are in the range of 7.4–8.6 [24]. WebCritical reagents like EDC and NHS, for example, are extremely hygroscopic and tend to hydrolyze and lose activity quickly upon contact with water. Be sure to let EDC equilibrate to room temperature (~20 minutes) prior to opening the EDC. Use the EDC as soon as possible after resuspension and use a fresh aliquot of EDC for each coupling reaction.
