PEG

Bis-propargyl-PEG3 is a crosslinker with alkyne groups at both ends of the molecule. The alkyne groups react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG3-t-butyl ester consists of an alkyne group and a t-butyl ester group. The alkyne groupreacts with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry reactions. The protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG3-acid is a reagent with an alkyne group and a carboxylic acid. The terminal carboxylic acid can form amide bond with primary amines (activation is needed). The alkyne can form triazole linkage with azide containing molecules via copper catalyzed reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG1-t-butyl ester is a PEG reagent containing an amino group with a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-Boc group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromo-PEG2-t-butyl ester is a PEG linker containing a bromide group and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

S-acetyl-PEG4-alcohol is a PEG linker containing a sulfur acetyl group which can be deprotected to form thiol groups. The hydroxyl group can undergo various reactions to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromo-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.

Amino-PEG1-acid is a PEG linker containing an amino group (NH2) with a terminal carboxylic acid (CO2H). NH2 group is reactive with carboxylic acids in the presence of coupling reagent such as EDC , or directly with NHS esters, to form a stable amide bond. Reagent grade, for research purpose.
