PEG

Fmoc-PEG2-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose.

Benzyl-PEG6-CH2CO2tBu is a PEG linker containing a benzyl protecting group and a t-butyl group. Both the benzyl and t-butyl groups are acid labile. The hydrophilic PEG linker increases the water solubility of the compounds in aqueous solutions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG3-alcohol is a PEG linker containing a maleimide group and a hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose.
