Introduction

BioGnost’s Oil Red O reagent is used for staining neutral triglycerides and lipids in frozen tissue sections, and lipoproteins in paraffin tissue sections. Oil Red O dye has largely replaces Sudan II and Sudan IV dyes because it provides stronger red coloration and it enables microscopic view of the section. It is a component of Oil Red O kit for histological visualization of lipids in tissues. The method is used with frozen tissue sections; lipids melt if processed in xylene or in alcohol.
