* Azides react with alkynes via the copper-catalyzed azide–alkyne cycloaddition reaction, as discussed in Click Chemistry—Section 3.1 (where these products are also described). † Reacts nonspecifically with available sites upon UV illumination. ‡ These reagents contain cryptic thiols that are exposed by disulfide reduction (SPDP or PEAS) or deacetylation (SATA) and can be subsequently disulfide-coupled to other thiolated molecules or thioether-coupled to maleimides or iodoacetamides. § EDAC couples amines to carboxylic acids (Derivatization Reagents for Carboxylic Acids and Carboxamides—Section 3.4). |
