t-Boc-Aminooxy-PEG7-amine is an aqueous soluble reagent with a Boc-protected aminooxy group and an amino group. The amino group is reactive with carboxylic acids, activated NHS esters. The protected aminooxy can be deprotected under mild acidic conditions and then can react with an aldehyde or ketone group to form a stable oxime linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

TCO-PEG3-triethoxysilane is a crosslinking PEG reagent containing a triethoxysilane moiety and a TCO group. Triethoxysilane is commonly used for surface modifications. This reagent can react with tetrazine-containing compounds to form a stable covalent bond without the catalysis of Cu or elevated temperatures. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity. Reagent grade, for research purpose.

CBZ-aminooxy-PEG8-t-butyl ester is a PEG linker containing a CBZ-protected aminoxy molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

TCO-PEG3-acid is a click chemistry PEG linker with a terminal carboxylic acid(CO2H) group. The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. This reagent can react with tetrazine-containing compounds to form a stable covalent bond. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG5-t-butyl ester is a PEG linker containing a maleimide group and a t-butyl ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. 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.

t-Boc-Aminooxy-PEG5-azide is a PEG5 compound with an azide group and Boc-protected amino group. It is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to form the free amine. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG13-t-butyl ester is a PEG linker containing a t-butyl ester. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

TCO-PEG3-NHS Ester is a PEG linker containing a TCO moiety and a NHS ester. The hydrophilic PEG spacer increases water-solubility and a decreases steric hindrance during ligation. This reagent can be used to label antibodies, proteins and other primary amine-containing macromolecules with TCO moiety. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG12-acid is an analog of DBCO-Acid with hydrophilic PEG linker and a DBCO group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds 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. Reagent grade, for research purpose.
