Thiol-mPEG

Performing the same measurements on samples where the gold surfaces had been passivated with mPEG-thiol (see section 4.1), leaving the subsequently self-assembled monolayers only at the bottom of the nanocavities, average fluorescence enhancement (across multiple samples) of 6.9 0.7 for Cy-5 has been obtained (46). In this case, the fill fraction for fluorescence emission was 3.1%. What the comparison of these measures shows is that the enhancements with and without... [Pg.495]

Several PEG reagents are available for site-specific PEGylation with protein cysteine thiols. mPEG-maleimide reacts to form a stable sulfide linkage via a 1,4-addition reaction of the thiol to the a,) -unsaturated site on the maleimide moiety [24]. [Pg.1400]

Thiol groups on proteins can also be linked to PEG via a disulfide bond. Either mPEG-OPSS of mPEG-thiolsulfonate is effective for this purpose. [Pg.1400]
