TCO-C3-PEG3-C3-amine is is a simple PEG analogue containing a TCO moiety and a free amine. This reagent can be used to derivatize carboxyl groups or activated esters (e.g. NHS esters) with the TCO moiety through a stable amide bond in the presence of of activators (e.g. EDC, or DCC). Hydrophilic PEG spacer improves water solubility. References: Sano K, Nakajima T, Miyazaki K, Ohuchi Y, Ikegami T, Choyke PL, Kobayashi H.
