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 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.

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

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 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.

18-(Bromoacetamido-PEG3-ethylcarbamoyl)heptadecanoic 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. 18-(Bromoacetamido-PEG3-ethylcarbamoyl)heptadecanoic 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.

Arachidonic acid is an essential fatty acid and a precursor for all prostaglandins, thromboxanes, and leukotrienes. Virtually all cellular arachidonic acid is esterified in membrane phospholipids where its presence is tightly regulated through multiple interconnected pathways. Free arachidonic acid is a transient, critical substrate for the biosynthesis of eicosanoid second messengers. Receptor-stimulated release, metabolism, and re-uptake of free arachidonate are all important aspects of cell signaling and inflammation.
