PEG

DBCO-mPEG, MW 30,000 is an azide reactive PEGylation reagent. DBCO reacts with azides (N3) efficiently without the presence of Cu catalyst which is known to be highly toxic for cells. Reagent grade, for research purpose.

Azidoacetic acid NHS ester is a compound containing an azide group and an NHS ester. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG3-Maleimide is provided as a kit of two vials. Azido-PEG3-Maleimide is not stable for storage; it needs to be made in situ by mixing Azido-PEG3-amine and Maleimide-NHS ester followed by shaking/ stirring for 30 minutes at room temperature. The maleimide group of the Azido-PEG3-Maleimide can react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Azide group enables Click Chemsitry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Diazo Biotin-PEG3-azide is useful for introducing a biotin moiety to alkyne-containing biomolecules using Cu(I)-catalyzed Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

1-(isopropylthio)-2,3,4,6-tetra-o-Ac-beta-D-Glucosylpyranose Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG10-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids 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.

Azido-PEG4-beta-D-glucose is a PEG linker containing one azide group and one D-glucose group. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. D-glucose increases solubility in aqueous media and increases the selectivity of the PEGylation reaction. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tos-PEG13-Tos is a PEG linker containing two tosyl groups. The hydrophilic PEG spacer increases solubility in aqueous media. 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.

Propargyl-PEG5-beta-D-glucose is a Click Chemistry-ready crosslinker containing a propargyl group and beta-D-glucose. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. D-glucose increases solubility in aqueous media and increases the selectivity of the PEGylation reaction. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
