(S)-TCO-PEG2-NH2 is an ADC Linker containing 2 PEG units. (S)-TCO-PEG2-NH2 can use its own TCO group to perform an inverse electron demand Diels-Alder reaction (iEDDA) with molecules with Tetrazine groups.
(S)-TCO-PEG3-NH2 is an ADC linker containing 3 PEG units. (S)-TCO-PEG3-NH2 can use its own TCO group to perform the inverse electron demand Diels-Alder reaction (iEDDA) with molecules with Tetrazine groups.
(S)-TCO-PEG7-NH2 is an ADC linker containing 7 PEG units. (S)-TCO-PEG7-NH2 can use its own TCO group to perform the inverse electron demand Diels-Alder reaction (iEDDA) with molecules with Tetrazine groups.
