PEG

Hydroxy-PEG8-t-butyl ester is a PEG linker containing a hydroxyl group with a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG8-alcohol consist of an amino (NH2) and a hydroxyl group (OH). The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The OH group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG12-alcohol is a water soluble conjugation PEG linker. NH2 group allows the reaction with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydroxyl group enables further derivatization. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG9-NHS ester is a PEG linker containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. 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.

Bis-PEG13-NHS ester is a PEG linker containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. 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-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.
