        Aminooxy-PEG1-azide is a short PEG linkerwith two functional groups, aminooxy (ONH2) and azide(N3). Aminooxy group can be used in bioconjugation by reaction with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The azide group can react with alkyne, BCN, DBCO via 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.

        Fmoc-PEG4-hydroxy is a PEG linker containing an Fmoc-protected amine and a hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

        DBCO-NHCO-PEG4-amine is a carboxyl-reactive building block with extended PEG spacer arm. The hydrophilic PEG spacer arm improves water solubility. In the presence of of activators (e.g. EDC, or HATU), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

        Acid-PEG9-NHS ester is a PEG linker containing a carboxylic acid and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. 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 NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

        DSPE-PEG-Amine, MW 2,000 is a PEG polymer containing DSPE and amine end groups. The DSPE-PEGs have been FDA approved for medical applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG increases the water solubility of the overall compound allowing for the delivery of the drug. The amine group can react with activated NHS ester to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
