PEG

N-(PEG1-acid)-L-Lysine-amido-Mal TFA salt is a PEG based linker with terminal malimide and carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. 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.

TCO-PEG8-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent. Reagent grade, for research purpose.

TCO-PEG2-DBCO is a short PEG linker featuring a trans-cyclooctene and a DBCO group. DBCO is a click chemistry handle which easily reacts with azides, while the TCO function readily reacts with tetrazine-containing compounds.

TCO-PEG6-DBCO is a PEG6 linker featuring a trans-cyclooctene and a DBCO group. DBCO is a click chemistry handle which easily reacts with azides, while the TCO function readily reacts with tetrazine groups in target compounds.

TCO-PEG24-DBCO is a monodisperse, long PEG linker featuring a trans-cyclooctene and a DBCO group. DBCO easily reacts with azides through click chemistry, while the TCO group readily reacts with tetrazine-containing compounds.

PEG 10,000 is a dihydroxyl PEG polymer which can be modified with new functional groups. Reagent grade, for research purpose.

PEG 20,000 is a homobifunctional PEG polymer with both hydroxyl terminus which can be further derivatized to other molecules. Reagent grade, for research purpose.

Amine Alkyne-PEG-acid, MW 2,000 is a click chemistry PEG derivative. The polymer can be used for coupling with activated ester molecule. The carboxylic acid (-COOH) is reactive with amine in the presence of activator, such as HATU and EDC. Reagent grade, for research purpose.

Amine Alkyne-PEG-OH, MW 10,000 can be coupled with NHS ester to form a stable amide bond. The alkyne moiety is reactive with azide via copper click chemistry to form a stable triazole bond. Reagent grade, for research purpose.
