PEG

Azido-PEG6-NHS ester consist of an azide(N3) and an NHS ester function group. The hydrophilic PEG spacer increases solubility in aqueous media. 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.

Amino-PEG7-azide consist of an amino (NH2) group with an azide (N3) group. The azide group enable click chemistry with alkyne, BCN, DBCO via Click Chemistry to form a stable triazole linkage, amine group is reactive with NHS active ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG3-NHS ester is an biotinylation compound that can couple with primary amino groups (-NH2). The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG5-azide is a click chemistry biotinylation reagent that can react with alkyne molecule to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PFP ester will react with primary amino groups (-NH2) to form stable, irreversible amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG4-alcohol is a PEG linker containing a maleimide group and a hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

endo-BCN-PEG4-t-butyl ester is a click chemistry linker containing a BCN group and a t-butyl protected carboxyl group. The BCN group can react with azide-tagged molecules. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The t-butyl ester can be converted to free acid under acidc condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

endo-BCN-PEG6-t-butyl ester is a click chemistry linker. The hydrophilic PEG spacer increases solubility in aqueous media. The BCN group can react with azide-tagged molecules. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. It can be converted to free acid under acidc condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

endo-BCN-PEG3-Boc-amine is a click chemistry linker containing a Boc-protected amine. The protected amine can be deprotected under mild acidic conditions. The BCN group enable copper free click chemistry with azide-tagged molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
