PEG

Ald-Ph-PEG2-t-butyl ester is a PEG linker with an aldehyde functional group. The t-butyl ester can be removed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Biotin-PEG4)-N-bis(PEG4-acid) HCl salt is a branched biotinylation reagent for labeling. The carboxylic acid groups can react with primary amines in the presence of EDC and HATU to form stable amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-boc-N-amido-PEG9-azide is a PEG reagent with an azide and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to free the amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG9-azide is a water soluble crsoolinking reagent containing an amino with an azide group. Amino group (NH2) is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyloxy carbonyl-PEG3-NHS ester is a PEG linker which contains a benzyl protecting group and an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The benzyl protecting group can be removed by hydrogenolysis. The PEG linker increases the compounds water solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG16-azide is a aqueous soluble PEGylation reagent. It is reactive with alkyne, BCN, DBCO via Click Chemistry to form a stable triazole linkage. PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azide-PEG16-alcohol is a monodisperse PEG linker containing an azide (N3) and a terminal hydroxyl group. N3 group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

2-((Azido-PEG8-carbamoyl)methoxy)acetic acid is a PEG linker containing an azide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a click chemistry branched linker. The propargyl groups can react with azide-bearing molecule via copper catalyzed Click Chemistry . The Boc group can be deprotected under acidic conditions to release amine group. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
