Cholesteryl Ester Analysis Service

Cholesteryl esters are a dietary lipid, which derived from cholesterol. Cholesteryl esters are formed when the body produces enzymes to produce a metabolic reaction with the cholesterol itself. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol.

Cholesteryl esters are largely spread in body fluids of animals (plasma lipoproteins) and may be also found in vessel walls as fatty streaks in atherosclerosis. Cholesteryl esters have a lower solubility in water due to their increased hydrophobicity.

Cholesterol Ester Targeted Lipidomics

Creative Proteomics provides you with efficient and accurate qualitative and quantitative detection services of cholesteryl ester through advanced chromatography and mass spectrometry platforms.

Our Cholesteryl Ester Analysis Service

Absolute quantification: Use external standard method to quantify, and use internal standard for correction, qualitative and quantitative is more accurate.
High sensitivity: We use liquid chromatography coupled with triple quadrupole mass spectrometers for cholesteryl esters analysis service (Triple Quad™ 6500 LC-MS/MS System).
