  • Analysis of critical parameters affecting retrieval efficiency.

    • Main Results:

    • A standard method yields generally good staining for neuroscience antibodies.
    • Some antigens remain difficult to retrieve or are not retrieved optimally.
    • Key factors identified include pH, temperature, and heating duration of the retrieval solution.

    Conclusions:

    • Microwave-stimulated antigen retrieval is a valuable tool, particularly in neuroscience.
    • Further optimization is needed for specific antigens.
    • Controlling solution pH, temperature, and heating time is crucial for successful antigen retrieval.
