N-(Azido-PEG3)-N-(PEG2-NH-Boc)-PEG3-acid is a branched click chemistry reagent. The azide (N3) group enable Click Chemistry reactions with alkynes such as Propargyl, DBCO and BCN. The terminal carboxylic acid can react with primary amine groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
TCO-PEG3-TCO is a reagent containing TCO moiety at both ends of the molecule. TCO group specifically and efficiently reacts with tetrazine. The hydrophilic PEG linker increases the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Biotin-PEG6-t-butyl ester is a PEG linker with a biotin and a t-butyl ester. The biotin group is used for the conjugation of proteins and can also be used for labeling. 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-Boc-PEG23-bromide is a PEG linker containing a bromide group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-PEG23-amine TFA salt 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 the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Tos-PEG3-methyl ester is a PEG linker with tosyl and methyl ester moieties. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG linker increases the water solubility of the compound. Methyl ester can be hydrolyzed under strong basic condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
