PEG

Cbz-N-amido-PEG5-acid is a PEG linker containing a CBZ-protected amino group and 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. The protected amine can be deprotected by acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-aminooxy-PEG12-acid is a PEG crosslinking compound. 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. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG3-alcohol is a Biotin PEG linker containing a biotin group and a terminal primary hydroxyl (OH) that reacts with a variety of functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-boc-N-amido-PEG7-amine is a PEG linker with an amino group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

1,7-BIS-BOC-1,4,7-TRIAZAHEPTANE contains two Boc protecting groups which can be removed under acidic conditions. The remaining free amines can further react with carbonyl moieties. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG1-t-butyl ester is a PEG linker containing a maleimide group and a t-butyl ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG1-CH2CO2-NHS has an azide group and an NHS ester moieties. The azide group can react with alkyne, BCN, DBCO via Click Chemistry. 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.

Acid-PEG13-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.

Fmoc-PEG3-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. 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 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.
