PEG

Mal-amido-PEG8-NHS is a PEG linker containing a maleimide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. 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.

NH-bis(m-PEG4) is a PEG building block containing an amino (NH2) group to be reactive with carboxylic acids or activated NHS esters, carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

NH-bis(m-PEG8) is a PEGylation reagent with an amino (NH2) group to be reactive with carboxylic acids or activated NHS esters, carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG2-CH2CO2H is a PEG linker with a benzyl protecting 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 benzyl protecting group can be removed via hydrogenolysis. The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose.

Lipoamido-PEG4-acid contains a lipoic acid group and a terminal carboxylic acid. Lipoic acid contains two sulfur atoms (at C6 and C8) connected by a disulfide bond and is thus considered to be oxidized although either sulfur atom can exist in higher oxidation states. 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 linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
