PEG

Biotin-PEG3-acid is a biotinylation reagent that can react with amine attached molecule. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein or macromolecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG3-azide is a biotinylation reagent that enable Click Chemistry reaction with alkyne, DBCO, BCN or prppargyl moiety to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tr-PEG5 is a PEG linker containing a trityl, alcohol protecting group and a terminal hydroxyl group. Trityl can be removed under acidic conditions. The hydroxyl group can undergo various reactions in order to further derivatize the compound. The hydrophilic PEG linkers increase the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tr-PEG4 is a PEG linker containing a trityl, alcohol protecting group and a terminal hydroxyl group. Trityl can be removed under acidic conditions. The hydroxyl group can undergo various reactions in order to further derivatize the compound. The hydrophilic PEG linkers increase the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tri(carboxyethyloxyethyl)amine HCl salt is a 3-arm branched molecule that can react with primary amino-containing entity in the presence of activator EDC or HATU Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG3-hydrazide is a hydrazide-activated biotinylation reagent used to label glycoproteins, carbohydrate-containing compounds that have oxidizable sugars or aldehydes. Hydrazine moiety reacts with an aldehyde to form semi-permanent hydrazone bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tos-PEG5-t-butyl ester is a PEG linker containing a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The tosyl group is a very good leaving group for nucleophilic substitution reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
