Lipids & Polymers

DSPE-PEG-endo-BCN, MW 2,000 is a click chemistry reagent with a BCN group attached to a polyPEG linker with hydrophobic lipid tails. The BCN group enables copper free click chemitry with azide-tagged molecules. Reagent grade, for research purpose.

N-bis(Amine-PEG8)-N-(PEG8-t-butyl ester) is a 3-arm PEG linker consisting of a t-butyl ester with two amino groups. The amino (NH2) groups are reactive with activated NHS esters or carboxylic acid. The t-butyl group can be deprotected under acidic conditions. Reagent grade, for research purpose.

14-(Azide-PEG5-ethylcarbamoyl)tridecanoic 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 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.

16-(Amine-PEG3-ethylcarbamoyl)pentadecanoic-t-butyl ester has an amine group on a PEG linker with an 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 group can be deprotected under acidic conditions. The polymer 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.

18-(Amine-PEG3-ethylcarbamoyl)heptadecanoic-t-butyl ester is a PEG linker with an amine group and an alkane tail that has a terminal t-butyl ester group. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The t-butyl 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.

18-(Bromoacetamido-PEG3-ethylcarbamoyl)heptadecanoic-t-butyl ester has a bromine on a PEG linker with a alkane tail that has a t-butyl ester group. The bromine (Br) can be used as a leaving group for nucleophilic substitution reactions. The t-butyl group can be deprotected under acidic conditions. It 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.

18-(NHS ester-methylamine-PEG3-ethylcarbamoyl)heptadecanoic-t-butyl ester is a PEG linker with an NHS ester group and an alkane tail that has a terminal t-butyl ester group. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The t-butyl 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.

18-(Bromoacetamido-PEG3-ethylcarbamoyl)heptadecanoic acid has a bromine on a PEG linker with an alkane tail that has a carboxylic acid group. The bromine (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. HATU) to form a stable amide bond. The polymer can form micelles spontaneously in water. This compound may also be used as a building block for lipids in nanotechnolgy and drug delivery. Reagent grade, for research purpose.

Arachidic Acid N-Hydroxysuccinimide Ester is a lipid comprised of a saturated fatty acid with a 20-carbon chain with a terminal NHS ester. 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.
