PEG

Propargyl-PEG5-acid has a propargyl group at one end and an acid group at the other end. The acid can react with primary amines to form a stable amide bond, activation will be needed. The PEG units enhances solubility of the molecule in aqueous environment. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG4-alcohol is a biotinylation reagent containing a primary hydroxyl (OH) that cn be derivatized. The PEG spacer provides greater solubility to labeled molecules compared to reagents having only hydrocarbon spacers. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-t-butyl ester has one of the functional groups protected by t-butyl group. The protection can be removed under acidic conditions. The propargyl group forms triazole linkages with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The PEG units help improving the water-solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG6-alcohol is a PEG reagent with one an amino group (NH2) and a hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-propargyl-PEG5 is a crosslinker containing propargyl groups at both ends. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form stable triazole linkages. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG2-amine is a biotinylation that can react with NHS ester or carboxylic acid in the presence of EDC or HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tos-PEG2-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.

Azido-PEG1-t-butyl ester is a azide containing molecules. it can react with alkyne, such as BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG3-alcohol consists of a hydroxyl group and a propargyl group. The propargyl group reacts with azide compounds in copper catalyzed azide-alkyne Click Chemistry to form a triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
