t-Boc-Aminooxy-PEG3-azide is a click chemistry reagent containing a t-Boc-aminooxy group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The protected aminooxy can be deprotected under mild acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromoacetamido-PEG3-acid is a PEG linker containing a bromide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. 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.

Bromoacetamido-PEG4-acid is a PEG linker containing a bromide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. 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.

Propargyl-PEG6-acid comprises propargyl and carboxylic acid functional groups. The acid group reacts with primary amines in the presence of activators (e.g. EDC, or HATU).The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The molecule has good solubility in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG6-t-butyl ester is a heterobifunctional linker consisting of an alkyne group and a t-butyl protected carboxyl group. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The t-butyl group can be hydrolyzed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-methyl-N-(t-Boc)-PEG4-acid is a PEG linker containing a t-Boc protecting group and a terminal carboxylic acid. The t-Boc protecting group is acid lablie. The terminal carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-aminooxy-PEG3 is an water soluble crosslinker containing two aminooxy groups. Aminooxy (ONH2) group can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond or a hydroxylamine linkage under reduction condition Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Azide-PEG3-Tos is a heterobifunctional PEG linker.The azide (N3) group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Tosyl group is a good leaving group for nucleophilic substitution reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Ald-Ph-PEG4-t-butyl ester contains a benzaldehyde group which can react with aminooxy (ONH2) bearing molecules. The t-butyl ester is a protecting group that can be removed under acidic conditions for further conjugation, PEG space improve aqueous solubility. Reagent grade, for research purpose.
