PEG

Aminooxy-PEG3-methane is a aminooxy-containing PEG reagent The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group is reactive with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. 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.

Aminooxy-PEG4-propargyl is a aldehyde reactive crosslinker. The aminooxy group reacts with an aldehyde or ketone group to form a stable oxime linkage. The propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. 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.

Propargyl-PEG4-5-nitrophenyl carbonate is heterobifunctional reagent with a propargyl group and nitrophenyl group. The propargyl group enales the formation of triazole linkage with azide compounds or biomolecules via copper catalyzed Click Chemistry. Nitrophenyl group is reactive towards the amino group of lysine by means of stable urethane linkages. The PEG units enhance the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PEG6000 is a polyPEG starting material for formulation or chemical modification. Reagent grade, for research purpose.

m-PEG4-(CH2)3-methyl ester is PEG linker containing a methyl ester end group. Methyl ester can be hydrolyzed under strong basic condition. The hydrophilic PEG chain increases the solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG4-(CH2)3-acid is a PEG linker containing a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG6-4-nitrophenyl carbonate is a PEG linker with a nitrophenyl carbonate group. The nitrophenyl carbonate is a good leaving group and can react with the amine groups of lysine residue by forming a stable urethan linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG2-azide is a click chemistry crosslinker molecule. The azide group enables PEGylation via Click Chemistry. The protected aminooxy can be deprotected under acidic conditions and then can react with an aldehyde or ketone group to form a stable oxime linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG8-azide is a aqueous soluble, homebifunctional PEG reagent The azide (N3) group cis very reactive with alkyne, such as BCN, DBCO via Click Chemistry to yield a stable triazole moiety Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
