PEG

Azido-PEG5-triethoxysilane is a PEG linker containing azido and triethoxysilane moieties. The azide can be used for copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN. The triethoxysilane moiety is used for surface modification. The hydrophilic PEG linkers increase the water solubility properties of compounds in aqueous media. Reagent grade, for research purpose.

TCO-PEG2-acid is a click chemistry linker containing a TCO (trans-cycloctene) and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators such as EDC. TCO reagent is highly reactive with tetrazine in an inverse electron demand Diels Alder (IEDDA) reaction followed by a retro-DA reaction. The hydrophilic PEG spacer increases solubility in aqueous media.

N-(Azido-PEG3)-N-Boc-PEG3-t-butyl ester is a protected multifunction linker. The azide group enables PEGylation via Click Chemistry. Boc and the t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG3-CH2CO2Me is a crosslinker containing an azide group and methyl ester. The azide group enables Click Chemistry reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Methyl ester can be hydrolyzed under strong basic condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

2-Amino-1,3-bis(carboxylethoxy)propane is a chemical reagent containing an amino group with two terminal carboxylic acids. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The terminal carboxylic acids 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.

N-(Biotin)-N-bis(PEG1-alcohol) is a branched PEG linker with biotin and hydroxyl moieties. The branches are all connected to a central nitrogen atom. The biotin group is used for the conjugation of proteins and can also be used for labeling. The alcohol groups can react to further derivatize the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-N-bis(PEG1-OH) is a small PEG linker compound with two terminal hydroxy groups and a Boc protected amino group. The hydroxy groups enable further derivatization or replacement with other reactive functional groups. Boc can be deprotected under acidic conditions. Reagent grade, for research purpose.
