Uniform PEG Thiolation Reagents

Payload Delivery Linkers and Modifiers | Uniform PEG Thiolation Reagents

Uniform PEG Thiolation Reagents are precisely synthesized polyethylene glycol molecules equipped with reactive thiol groups for targeted conjugation to biomolecules or surfaces.

These reagents enable site-specific attachment through stable thiol-based chemistry. The uniform PEG chains improve solubility, reduce immunogenicity, and provide flexible spacers that enhance the stability and functionality of bioconjugates. Their consistent molecular weight ensures reproducible performance in drug delivery, protein modification, and surface functionalization.

We sell uniform PEG thiolation reagents including PEG SATA, methoxytrityl-S, and thioacetyl modifiers, which enable controlled thiol group introduction for precise bioconjugation and payload delivery applications.
