Intense Lipid Staining: Sudan IV selectively dissolves in and stains neutral lipids (triglycerides, fatty acids, cholesterol esters) a striking deep red. This robust staining provides excellent contrast and clarity for identifying fat deposits within cells and tissues.
Highly Specific for Neutral Fats: The dye's non-polar nature ensures its high specificity for neutral lipids, making it an ideal choice for:
Demonstrating Adipose Tissue: Clearly outlines individual adipocytes and fat lobules, essential for studies in obesity, metabolic disorders, and body composition.
Detecting Fatty Degeneration (Steatosis): Critical for diagnosing conditions where abnormal lipid accumulation occurs in organs such as the liver, heart, or kidney.
Optimal for Frozen Sections: Since lipids are typically lost during routine paraffin processing, Sudan IV is designed for use with fresh or fixed frozen sections, ensuring the preservation and accurate demonstration of fat.
Histology Grade Purity & Saturation: Our Sudan IV is prepared to stringent histology-grade standards and provided as an optimized solution (often saturated in an alcoholic solvent like 99% isopropanol or 70% ethanol), ensuring maximum dye uptake and consistent staining efficacy.
Consistent Performance: Every batch undergoes rigorous quality control to guarantee reliable staining intensity and dependable results, ensuring reproducibility across your diagnostic and research studies.
