I have prepared a chitosan-allicin complex in different concentrations, as am from nanotechnology background i don't know what kind of test gives me the exact results to study the impact of the drug on cholesterol and low density lipoproteins!
To check the effect of the drug on cholesterol and Oxi-LdL, it may be necessary for you to conduct a short-term in vivo experiment. Blood is the main sample to check. Also if you want to see how this drug affects genes related to cholesterol metabolism, you may try an in vitro model of liver.
As to LDL oxidation read our article: Title: A SPECTROPHOTOMETRIC ASSAY FOR LIPID PEROXIDES IN SERUM-LIPOPROTEINS USING A COMMERCIALLY AVAILABLE REAGENT
