        Thiol-PEG4-acid is a PEG linker containing a thiol group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

        Sulfo DBCO-Amine can be used to derivatize carboxyl-containing molecules or activated esters (e.g. The NHS ester) with DBCO moiety through a stable amide bond. The low mass weight will add minimal spacer to modified molecules and the hydrophilic sulfonated spacer arm will greatly improve water solubility of DBCO derivatized molecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
