Popis

Application

NHS ester-a-TCO is an axial trans-cyclooctene (a-TCO) for bioconjugation and protein labeling. NHS ester-a-TCO has an amine-reactive NHS ester, and the a-TCO reacts rapidly with tetrazines through Diels–Alder reactions, a type of bioorthogonal, copper-free click chemistry. As demonstrated by the Joe Fox lab in Pigga, et al, a-TCOs are more reactive and hydrophilic than standard TCOs, providing favorable physiochemical properties for live-cell and in vivo labeling.
