PEG

DBCO-PEG2-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose.

Methyltetrazine-PEG4-Amido-PEG8-Mal-3,4-Dibromo is an aqueous soluble amine-containing click chemistry crosslinker. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene) Reagent grade, for research purpose. The dibromomaleimide group allows for two points of attachement because both of the bromine atoms can be substituted.

4-Arm PEG5-DBCO is a 4-arm branched PEG linker with four DBCO moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose.

Carboxy-Amido-PEG4-t-Boc-N-amido is a PEG linker containing a terminal carboxylic acid and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. 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. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose.

Amine-PEG-amine HCl salt, MW 2,000 is an HCl salt of a homobifuctional diamines polyPEG. This compound is useful for modification of biological molecules by covalent conjugation as a strategy to overcome disadvantages associated with some biopharmaceuticals. Reagent grade, for research purpose.

DBCO-PEG-NH-Boc, MW 5,000 is a polyPEG linker with a DBCO group and a Boc-protected amine. The DBCO can undergo copper-free Click Chemistry reactions with azides. The Boc protecting group can be removed under acidic conditions to further react. The PEG chain helps with water solublity and flexibilty of the crosslinking agent. Reagent grade, for research purpose.

3-Arm PEG5-DBCO is a crosslinker that can react with azide compounds or biomolecules via copper-free Click Chemistry reactions. Reagent grade, for research purpose. The DBCO can undergo copper-free Click Chemistry reactions with azides. The PEG chain helps with water solublity and flexibilty of the crosslinking agent. Reagent grade, for research purpose.

Carboxy-Amido-PEG5-Amine is a PEG reagent containing an amino (NH2) and a terminal carboxylic acid group. The hydrophilic PEG unit increases hydrophilicity. NH2 amine group is reactive with carboxylic acids in the presence of coupling reagent such as EDC , or directly with NHS esters, to form a stable amide bond. Reagent grade, for research purpose.

Carboxy-Amido-PEG5-N-Boc is a PEG linker containing a terminal carboxylic acid and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, HATU) to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose.
