PEG

m-PEG1-NHS ester is a PEG linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG2)-N-Boc-PEG3-acid is a multifunction PEG linker. The azide group enables PEGylation via Click Chemistry. Boc can be deprotected under acidic conditions. The terminal carboxylic acid can react with primary amino groups in the presence of activators (e.g. EDC, or HATU). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG2)-N-Boc-PEG4-acid is a N-Boc protected, branched PEG linker with a azido and a terminal carboxylic acid. The azide group enables PEGylation via Click Chemistry. The protected amine can be deprotected under acidic conditions. The terminal carboxylic acid can react with primary amino groups in the presence of activators (e.g. EDC, or HATU). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Propargyl-PEG4)-N-bis(PEG4-acid) is a branched crosslinking reagent with a propargyl group and two terminal carboxylic acids. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acids can react with primary amino 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.

N-(Azido-PEG2)-N-Boc-PEG4-t-butyl ester is a very useful branched PEG reagent with a terminal azide group, Boc protected amine, and a terminal t-butyl ester. The azide groups is very reactive with alkyne such as DBCO, BCN and propargyl reagnet via Click Chemistry. The protected amine can be deprotected under acidic conditions, and the t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

2-(Biotin-amido)-1,3-bis(carboxylethoxy)propane is a branched biotinylation reagent. The carboxylic acid groups can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Acid-PEG1-t-butyl ester is a PEG linker containing a t-butyl protected carboxyl group with a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Acid-PEG2-t-butyl ester is a PEG linker containing a t-butyl protected carboxyl group with a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Acid-PEG6-t-butyl ester is a PEG linker containing a t-butyl protected carboxyl group with a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose.
