PEG

N-(Propargyl-PEG4-carbonyl)-N-bis(PEG1-methyl ester) is a crosslinker that can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. The methyl ester groups can be hydrolyzed, reduced, or substituted under different conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG3)-N-Biotin-PEG4-methyl ester is a branched PEG linker with a biotin group and terminal azide group. The azide group enables click chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-aminooxy-PEG7 molecule contains two aminooxy groups. The hydrophilic PEG spacer increases solubility in aqueous media. Aminooxy (ONH2) group is reactive with an aldehyde to form an oxime bond or a hydroxylamine linkage under reduction condition Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
