PEG

Azido-PEG8-amine is a aqueous soluble heterobifunctional reagent consisting of an azide group and a free amine group. The azide group enables Click Chemistry. The amine group is reactive with carboxylic acids, activated NHS esters. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG10-amine is a bifunctional crosslinker with 10 PEG units . The azide group can participate in copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN moieties to form triazole groups. The amine group can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The hydrophilic PEG linker increases the water solubility of the compound in aqueous solutions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG11-amine is a water soluble PEG compound. The azide group enables Click Chemistry. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG arm increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG4-alcohol is a PEGreagent with a Boc-protected aminooxy group and an alcohol group. The hydrophilic PEG spacer increases solubility in aqueous media. The protected aminooxy can be deprotected under mild acidic conditions and then can react with an aldehyde to form a stable oxime linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG4-Tos is a bifunctional crosslinker reagent with a t-Boc-aminooxy group and a tosyl group. The tosyl group is a very good leaving group for nucleophilic substitution. The protected aminooxy can be deprotected under mild acidic conditions. PEG5 spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-NHS Ester is a very popular amine-reactive click chemistry reagent. It can be used to modify an amine-containing molecule in organic solvents (limited solubility in aqueous media). It reacts with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic pH to form covalent bonds. The low mass weight will add minimal spacer to modified molecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG5-alcohol is a PEG linker with a acid labile, benzyl group and a reactive primary alcohol. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-PEG2-bromide is a PEG linker containing a Boc protected amine and a bromide group. The protected amine can be deprotected under mild acidic conditions. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-PEG3-bromide is a PEG linker containing a Boc protected amine and a bromide group. The protected amine can be deprotected under mild acidic conditions. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose.
