N-azidoacetylglucosamine-tetraacylated (Ac4GlcNAz) is an azido-tagged analogue of N-acetylglucosamine (GlcNAC). It features azide functionality on the N-acyl side chain and is acetylated to aid in cell membrane permeation. Once in the cell, the acetylated compound is deprotected and takes part in the hexosamine biosynthetic pathway by action of GlcNAc kinase. The resulting modified proteins are detected by the addition of fluorescent tags under Cu(I)-catalyzed azide-alkyne cycloaddition conditions. Reagent grade, for research purpose.

PEG21 is a polymer of ethylene glycol subunits with two terminal hydroxyl groups. The hydroxyl groups can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media. The water solubility properties of the PEG chain are enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG7-alcohol is a aqueous soluble PEGylation reagent The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Hydroxy group further increase the reagnt's water solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

NH-bis(PEG4-OH) is a branched PEG4 reagentr. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls, etc. The hydroxy groups enable further derivatization or replacement with other reactive functional groups.
