PEG

PC Azido-PEG11-NHS carbonate ester is a photocleavable linker. It can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Azide nable click chemistry with alkyne or DBCO, BCN reagents. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG4)-N-bis(PEG4-NHS ester) is a branched chemistry linker with two NHS ester groups and a terminal azide. The NHS ester is used to label the primary amines (-NH2) of proteins and other amine-attached molecules. PEG arm allows for enhanced hydrophilic properties. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG11-[4-(5-(1-hydroxyethyl)-2-methoxy-4-nitrophenoxy)-butanamide] Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG36-t-butyl ester is a monodisperse long PEG linker molecule. Azide (N3) group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG-NHS ester, MW 5,000 is an amine reactive PEG polymer. The NHS ester is reactive with primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amino molecules. Reagent grade, for research purpose.

(4-methoxyphenyl)diphenylmethylamino-PEG7 Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG10-DBCO is a monodisperse click chemistry linker containing two terminal DBCO groups with hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Diketone-PEG11-Diketone Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Diketone-PEG11-PFP ester is a PEG linker containing a diketone group and a PFP ester group, an activated ester that reacts with primary amines to form amide bonds. PFP ester has been found to be more stable than other amine reactive groups because it is less likely to undergo hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media.
