Specific Lipid Staining: Sudan III selectively dissolves in and stains neutral lipids (triglycerides, fatty acids, cholesterol esters) a distinctive orange-red color. This non-polar interaction makes it highly specific for fat droplets within cells and tissues.
Demonstration of Adipose Tissue: Ideal for clearly visualizing and quantifying lipid content in adipocytes, making it essential for research in obesity, metabolic syndrome, and related conditions.
Detection of Fatty Degeneration: Crucial for identifying conditions like fatty liver (steatosis) or lipid accumulation in other organs, providing important diagnostic and research insights.
Histology Grade Purity & Saturation: Our Sudan III is prepared to stringent histology-grade standards and provided as a saturated solution, ensuring optimal dye concentration and consistent staining efficacy for reliable results.
Compatible with Frozen Sections: As lipids are often extracted by routine paraffin embedding, Sudan III is typically used with frozen sections, where lipids are preserved. Our formulation is optimized for such applications.
Consistent Performance: Every batch undergoes rigorous quality control to guarantee consistent staining intensity and dependable performance, ensuring reproducibility across your studies.
