PEG

Methyltetrazine-PEG12-Acid is a click chemistry PEG reagent, which can couple with amine-containing compound or macromolecule in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Methyltetrazine enable fast click chemistry with TCO ((trans-cycloctene) under mild condition. The hydrophilic PEG spacer increases water-solubility and methyl group enhances the stability of tetrazine moiety. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-Biotin-PEG23 is a PEG linker with two biotin moieties. The biotin molecule is commonly used for conjugation and labeling. The hydrophilic PEG linker makes the compound more soluble in water. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG23-Amine is a monodisperse PEG linker containing two terminal amine moieties. The amine groups are reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Hydroxy-PEG3-acrylate is a PEG linker containing a hydroxyl group and an acrylate group. The hydroxyl group allows for further derivatization of the compound. The acrylate group enables Michael addition reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-NMe-PEG4-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-propargyl-PEG8 consists of two propargyl groups which can react with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry to form stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Iodo-PEG3-Azide is a PEG linker containing iodide and azide moieties. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The iodide is a very good leaving group for nucleophilic substitution reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG36-acid is a aqueous soluble, monodisperse PEG reagent comprising an azide group with a terminal carboxylic acid. The azide group can react with alkyne, BCN, DBCO via Click Chemistry. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG12-propargyl can participate in copper catalyzed Click Chemistry reactions with biomolecules that contain azide. The t-Boc protected amine can be deprotected under mild acidic conditions. The PEG spacer helps improve the water-solubility of the molecule. Reagent grade, for research purpose.
