Fmoc-NH-pentoic acid-NHS-SO3Na is a linker containing an Fmoc-protected amine and sulfonated succinimidyl ester. This reactive moiety is sulfonated to increase water solubility. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
5-Maleimido-pentanoic NHS ester contains a maleimide group and an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. 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.
endo-BCN-pentanoic acid is a click chemistry reagent containing a BCN group and a terminal carboxylic acid. The BCN group can react with azide-tagged compounds or biomolecules. 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. Please contact us for GMP-grade inquiries.
DBCO-PEG13-DBCO is a long chain click chemistry reagent DBCO will react with azide-bearing compounds or biomolecules without copper catalyst. The hydrophilic PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(Amino-PEG2)-N-bis(PEG3-azide) is a branched click chemistry reagent containing two azides (N3) and an amine moiety. The azide can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. An amine is reactive with activated NHS esters or carboxylic acid (CO2H) in the presence of HATU or EDC. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-C2-PEG4-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 solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
