Phosphorylcholine chloride is a component of drug delivery micelles, which improves the efficiency of cellular internalization and increases the cytotoxicity of cytotoxins carried in micelles in HeLa cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Phosphorylcholine chloride (2 μg; ip; once every two weeks for 4 months) induces the production of anti-PC and anti-oxLDL antibodies, increases mature B cells in the spleen, and reduces atherosclerotic lesions in the aortic root in mouse models[4].
