PEG

N-(Boc-PEG5)-N-bis(PEG4-acid) is a branched PEG reagent, it can be conjugated with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Boc protection can be removed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-N-bis(PEG4-acid) is a branched PEG linker with a Boc protected amino group and two terminal carboxylic acids. The protected amine can be deprotected under acidic conditions. Carboxylic acids can react with primary amino groups in the presence of EDC or HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG2)-N-Boc-PEG3-t-butyl ester is a branched PEG molecule with a terminal azide group, Boc protected amine, and a terminal t-butyl ester. The azide group enables Click Chemistry. The Boc protected amine can be deprotected under acidic conditions, and the t-butyl protected carboxyl group can be hydrolyzed nder mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Hydroxy-PEG3-methyl ester is a PEG linker containing a hydroxyl group and a methyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Methyl ester can be hydrolyzed under strong basic condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG6-Amine is a PEG linker with two amino groups. The amino groups are reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-N-bis(PEG4-NHS ester) is a branched PEGylation reagent. The NHS esters can be used to label proteinsor other amine-attached molecules. Boc can be removed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG3-propargyl enables formation of triazole linkage with azide-bearing compound via copper catalyzed Click Chemistry. Under mild acidic conditions, t-Boc group can be removed to yield the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG1-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.

Cbz-N-amido-PEG15-amine contains a Cbz-protected amino group and a terminal amine group. The Cbz protecting group can be removed under acidic conditions. The terminal amine can react with carboxylic acid, activated NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
