Hi everyone I have to perform the Foam Cell Assay with OIL RED O staining. Can you recommend a compound that inhibits LDL oxidation? Also, can anyone recommend oxLDL to use?
There aren't a lot of non-cytotoxic choices for LDL anti-oxidants. Also macrophages can take up native LDL.

You might consider using an inhibitor of a major LDL/ ox-LDL uptake pathway, such as sulfo-N-succinimidyl oleate for inhibition of CD36. pretreat with inhibitor then add Ox-LDL (We use 100 micromolar) We buy both ox-LDL and DiI-labeled-oxLDL from Invitrogen.
