PEG

m-PEG3-Ms is a PEG linker containing a mesyl group. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The water solubility properties of the PEG linker in enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG4-PFP ester is a PFP active ester containing a DBCO group which can undergo copper-free Click Chemistry with azide (N3). The PFP ester moiety is reactive with amine groups. PFP esters have been are stable compounds and are less susceptible to undergo hydrolysis. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG12-NHS ester is a PEG linker containing a maleimide group and an NHS ester group. 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. Please contact us for GMP-grade inquiries.

m-PEG5-triethoxysilane is a PEG linker containing a triethoxysilane moiety which is commonly used for surface modification. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media. The water solubility of the PEG chain is enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

endo-BCN-PEG2-NHS ester is aclick chemistry crosslinker containing an NHS ester group. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group is reactive with azide-tagged biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG12-NHS ester is a monodisperse PEG linker containing a t-Boc protected aminooxy group and an NHS ester moiety, which can conjugate with amino-containing molecule. The hydrophilic PEG spacer increases solubility in aqueous media. The t-Boc can be removed under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG6-Ms is a PEG linker containing a mesyl group. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility 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.

Amino-PEG9-alcohol is a PEG linker containing amine and hydroxyl moieties. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydroxyl group can react to allow for further derivatization of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG9-propargyl is an alkyne linker that can be used in Click Chemistry reactions with azides to yield a stable triazole linkage; copper is required for catalyzation. Under mild acidic conditions, the Boc group can be removed to form a free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
