    Area of Science:

    • Biochemistry
    • Analytical Chemistry
    • Lipidomics

    Background:

    • Accurate lipid profiling is crucial for understanding cellular function and disease.
    • Traditional lipid extraction and separation methods can be time-consuming and require significant sample manipulation.

    Purpose of the Study:

    • To develop a direct, efficient method for lipid class separation and quantification from frozen tissue sections.
    • To establish a streamlined workflow for lipidomic analysis.

    Main Methods:

    • Frozen tissue sections were applied directly onto silica gel plates.
    • Lipids were separated using various solvent systems.
    • Lipid classes were quantified via direct transmission densitometry after chromic acid-sulfuric acid staining.

    Main Results:

    • Successful separation of distinct lipid classes directly from tissue sections.
    • Demonstrated quantitative accuracy of the densitometric approach for lipid profiling.
    • The method proved effective for analyzing lipids in frozen biological samples.

    Conclusions:

    • This direct silica gel plate method offers a simplified and effective approach to lipid class analysis.
    • The technique is suitable for rapid lipid profiling of frozen tissue specimens.
    • This method holds potential for advancing lipidomic research and diagnostics.
