The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tri(propargyl-NHCO-ethyloxyethyl)amine is a crosslinker that can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG2-DBCO is a PEG linker containing two terminal DBCO groups. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. T Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-amido-PEG-CH2COOH, MW 10,000 is a heterofuctional polyPEG with a Fmoc protecting group. The coupling of carboxylic acid with amines can be easily done by using activator, such as EDC or HATU. The Fmoc can be removed in a basic condition to obtain a free amine. Reagent grade, for research purpose.

N-(DBCO-N-amido-PEG4)-N-Biotin-PEG4-t-Boc-Hydrazide is a heterotrifunctional PEG linker containing Fmoc, biotin, and a Boc-protected hydrazide moieties. Biotin has strong binding affinity with avidin and can be used in detection, immobilization, targeting, labeling as well as nonradioactive purification. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The Boc can be deprotected under mild acidic conditions to form a reactive hydrazide, which can then be coupled with various carbonyl groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azidobutanamide-Tri-(m-PEG8-ethoxymethyl)-methane is a branched PEG linker with an azide group and three terminal methoxy groups. The azide group enables PEGylation via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-bis(PEG2-propargyl)-N-(PEG2-amidoPEG1)-N-(bis(PEG2-propargyl) is a branched PEG linker with four terminal alkyne groups. The alkyne groups can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Cbz-N-amido-tri-(carboxyethoxymethyl)-methane is a aqueous soluble PEG linker with an Cbz group with three terminal carboxylic acids. The Cbz protecting group can be removed under acidic conditions.
