PEG

N-(4-pentynoyl)-galactosamine tetraacylated (Ac4 GalNAl) can be used for the identification and characterization of specific surface groups of glycoproteins. The alkyne groups can react with azides via copper-catalyzed Click Chemistry. The acetyl groups on the glucose allow for easier penetration through the cell membrane. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG-Mal, MW 2,000 is a maleimide PEGylation reagent which is reactive with thiol at pH 6.5 to 7.5. Reagent grade, for research purpose.

m-PEG-Butyraldehyde, MW 5,000 is a PEG polymer with an aldehyde which is reactive with hydrazide or aminooxy groups for biomolecular probes and labeling. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose.

m-PEG-5,000-Succinimidyl Succinate is a linear amine (NH2) reactive PEG polymer for PEGylation. Reagent grade, for research purpose.

bis-PEG2-endo-BCN is a click chemistry reagent, The BCN group enable copper free click chemitry with azide-tagged molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG-Succinimidyl Valerate, MW 20,000 is a thiol reactive PEG polymer with a terminal active ester which is reactive with NH2 to form a stable amide bond. Reagent grade, for research purpose.

Amine-PEG-amine, MW 20,000 is a homobifunctional PEG polymer with amine groups at each terminus. The reactivty of amine with NHS esters may be useful for many applications, such as targeted drug delivery, nanoparticles, microcapsules liposomes etc. Reagent grade, for research purpose.

Amine-PEG-amine, MW 35,000 is a bifunctional polyPEG with two terminal amines. Due to its reactivity with many functional groups, PEG-diamines is widely use for modification of proteins, peptides, cells, drugs etc. PEGylation increases solubility. Reagent grade, for research purpose.

Bis-PEG11-NHS ester is a PEG linker containing two NHS ester groups. 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. Reagent grade, for research purpose.
