endo-BCN-PEG2-amine is a heterobifunctional PEG linker containing a BCN and an amine group. The BCN group can react with azide-tagged molecules. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Bromo-PEG2-methyl ester is a PEG linker containing a bromide moiety and a methyl ester. The bromide (Br) is a very good leaving group for nucleophilic substitution 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.
Amino-PEG12-CH2CO2-t-butyl ester is a water soluble PEG linker containing an amino group with a t-butyl protected carboxyl group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
N-(Azido-PEG4)-N-bis(PEG4-acid) is a 3-arm branched PEG linker. The azide can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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.
5-(Azido-PEG4)-pent-2-yn-1-Ol is a PEG linker containing an azide group and a terminal hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
