PEG

PEG14 is a PEG chain consisting of 13 ethylene glycol subunits and two terminal hydroxyl groups. The hydroxyl groups can participate in reactions to further derivatize the compound. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PEG6-Tos is a PEG linker containing a hydroxyl group with a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The tosyl group is a very good leaving group for nucleophilic substitution reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Thiol-PEG3-alcohol is a PEG linker containing a thiol group and a hydroxyl group. 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 hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
