    Acid alpha-naphthyl acetate esterase activity identifies most mouse peripheral T cells. Combining this esterase assay with lymphocyte surface markers offers a new way to study T cell differentiation.

    Area of Science:

    • Immunology
    • Cell Biology

    Background:

    • Peripheral T cells in mice predominantly exhibit acid alpha-naphthyl acetate esterase activity.
    • Esterase activity can be easily demonstrated using cytochemical or histochemical methods.
    • These methods are applicable to various sample types, including tissue sections and smears.

    Purpose of the Study:

    • To investigate the utility of acid alpha-naphthyl acetate esterase activity in characterizing peripheral T cells.
    • To explore the potential of combining esterase activity assays with lymphocyte surface marker analysis.
    • To examine T cell differentiation pathways using this combined approach.

    Main Methods:

    • Cytochemical and histochemical staining for acid alpha-naphthyl acetate esterase activity.
    • Immunophenotyping using lymphocyte surface markers.
