Stearic acid-PEG-amine, MW 1,000 is an amphiphilic PEG polymer which forms micelles in an aqueous solution. The terminal amine can react with an NHS ester to form a stable amide linkage. The aliphatic chain of stearic acid can be used to encapsulate or congregate hydrophobic therapeutic agents while the PEG chain enhances overall solubility of the polymer. Reagent grade, for research purpose.

Stearic acid-PEG-amine, MW 2,000 can be used to prepare nanoparticles or micelles in drug nanocarrier system. Its amphiphilic property enhances drug solubility, formulation, and bioavailability. Reagent grade, for research purpose.

Stearic acid-PEG-amine, MW 3,400 is an amino polydisperse PEG for coupling with an NHS ester to form an amide bond. The amphiphile PEG can be used for designing nanoparticles/micelles in a drug delivery system. Reagent grade, for research purpose.

Stearic acid-PEG-amine, MW 10,000 is a PEGylated lipid which exhibits both hydrophobicity and hydrophilicity property. The polymer is an excellent liposome-formation material for therapeutics delivery. The amine moiety enables coupling with an NHS ester or carboxylic acid in the presence of activator, such as HATU or EDC. Reagent grade, for research purpose.

Stearic acid-PEG-Mal, MW 1,000 is an amphiphatic PEG polymer which forms micelles in an aqueous solution for drug-loaded nanoparticles. The terminal maleimide can react with thiol/cysteine via condensation reaction to form a stable thioether bond. Reagent grade, for research purpose.

Stearic acid-PEG-Mal, MW 2,000 is a heterobifunctional polyPEG with 18-carbon aliphatic chain and maleimide. The polymer has stearic acid as the hydrophobic tail and PEG as the hydrophilic chain, therefore it forms micelles in water. Maleimide can react with thiol or cysteine to generate thiosuccinimide molecule which is commonly used for bioconjugation. Reagent grade, for research purpose.

Stearic acid-PEG-Mal, MW 3,400 is a lipophilic thiol-reactive PEG polymer. The stearic acid can be used to encapsulate hydrophobic therapeutic agents while the PEG chain increases overall water solubility and biocompatibilty. Reaction between maleimide and thiol generates thioether linkage. Reagent grade, for research purpose.

Stearic acid-PEG-Mal, MW 5,000 is an amphiphilic PEG polymer which forms micelles in an aqueous solution. The terminal maleimide can react with thiol/cysteine via Michael-addition to form a thiosuccinimide molecule. The aliphatic chain of stearic acid can be used to encapsulate or congregate hydrophobic therapeutic agents while the PEG chain enhances overall solubility of the polymer. Reagent grade, for research purpose.

2-Octydecanoic acid is a saturated fatty acid with a long aliphatic tail consisting of 17 carbon atoms and a carboxylic acid group.
