Important Product Information:
TCO-NHS Ester is not recommended for labeling of proteins in aqueous buffers due to poor level of activation of labeled proteins (Rahim, M.K., et al., Bioconjugate Chem. 2015, 26, 352-360). TCO-PEG4-NHS Ester and TCO-PEG12-NHS Ester are well suited for protein and antibody labeling in aqueous buffers.
