Azidobutanamide-tri-(carboxyethoxymethyl)-methane is a aqueous soluble PEG linker with an azide group with three terminal carboxylic acids. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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.
Amine-PEG4-Amido-tri-(carboxyethoxymethyl)-methane is a branched PEG linker with an amine and three terminal carboxilic acid groups. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The terminal carboxylic acid groups 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.
Boc-NH-Tri-(carbonylethoxymethyl)-methane is a branched PEG linker with a Boc-protected amino and three terminal carboxilic acid groups. The Boc group can be deprotected under mild acidic conditions to form the free amine. The terminal carboxylic acid groups 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.

Biotin-PEG4-amido-methyltetrazine is an aqueous soluble PEGylation reagent containing a biotin and a methyltetrazine group. Methyl group improves the stability and hydrophilic PEG spacer increases water-solubility. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene). The spacer arm helps to minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(TCO)-N-bis(PEG4-acid) is a branched click chemistry reagent with a terminal TCO group and two terminal carboxylic acids. This reagent can react with tetrazine-containing molecule 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. The terminal carboxylic acids can react with primary amino groups in the presence of activators (e.g. EDC, HATU ). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(TCO)-N-bis(PEG4-NHS ester) is a branched click chemistry reagent with a terminal TCO group and two terminal NHS esters. This reagent can react with tetrazine-containing molecule 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. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose.
