mPEG Thiol

mPEG Thiol (methoxy polyethylene glycol thiol) is a Uniform PEG Modifier featuring a terminal thiol (-SH) group, enabling selective conjugation to maleimide-, gold-, or other thiol-reactive surfaces and biomolecules. This reagent forms stable thioether or Au–S bonds, making it ideal for surface modification, nanoparticle functionalization, and PEGylation of proteins or peptides.

The uniform mPEG structure ensures predictable molecular behavior, excellent solubility, and enhanced biocompatibility for applications in drug delivery, diagnostics, and nanomedicine.
