20-(Amine-PEG3-ethylcarbamoyl)nonadecanoic-t-butyl ester has an amine group on a PEG linker with a alkane tail that has a t-butyl ester group. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions. 20-(Amine-PEG3-ethylcarbamoyl)nonadecanoic-t-butyl ester is a self-assembling PEG reagent which may form micelles in water. This compound may also be used as a building block for lipids in nanotechnolgy and drug delivery. Reagent grade, for research purpose.

16-(Azide-PEG4-ethylcarbamoyl)pentadecanoic-t-butyl ester is a PEG linker with an azide group and an alkane tail that has a terminal t-butyl ester group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The polymer can form micelles spontaneously in water. It may also be used to prepare more complex lipids for nanoparticles for drug delivery. Reagent grade, for research purpose.

Iodoacetamido-PEG3-NHS ester is a PEG reagent containing an Iodoacetamide group and a Boc-protected amino group. The iodoacetamide group is an alkylating agent that can be used to bind covalently with the thiol group. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose.

N-(Propargyl-PEG2)-DBCO-PEG3-Amine, TFA salt enables formation of triazole linkage with azide-bearing compound via copper catalyzed Click Chemistry. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry. Reagent grade, for research purpose.

20-(Bromoacetamido-PEG3-ethylcarbamoyl)nonadecanoic acid has a bromide group on a PEG linker with a alkane tail that has a carboxylic acid group. The bromide (Br) can be used as a leaving group for nucleophilic substitution reactions. 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. 20-(Bromoacetamido-PEG3-ethylcarbamoyl)nonadecanoic acid is a self-assembling PEG reagent which may form micelles in water. This compound may also be used as a building block for lipids in nanotechnolgy and drug delivery. Reagent grade, for research purpose.

DBCO-PEG-amine, MW 3,400 is a polyPEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research use only.

Azido-PEG-CH2CO2-NHS, MW 2,000 is a poly PEG linker containing an azide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. Azide (N3) group can react with alkyne, BCN, DBCO via Click Chemistrye. 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.

DBCO-Amido-tri-(carboxyethoxymethyl)-methane is a aqueous soluble PEG linker with an DBCO group with three terminal carboxylic acids. The DBCO groups is commonly used for Click Chemistry reactions. 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.
