An improved method for purification of lymphocytes.

U Carpentieri, L Thorpe, L A Sordahl

    American Journal of Clinical Pathology
    |December 1, 1977
    PubMed
    Summary

    A new method efficiently isolates pure human lymphocytes from small blood samples. This technique preserves the B cell/T cell ratio, yielding ample material for biochemical research.

    Area of Science:

    • Immunology
    • Cell Biology
    • Biochemistry

    Background:

    • Accurate isolation of pure human lymphocytes is crucial for immunological and biochemical research.
    • Existing methods may suffer from low yields or compromised cell viability and ratios.

    Purpose of the Study:

    • To describe a novel, efficient method for isolating pure human lymphocytes.
    • To ensure high yield, preservation of cell ratios, and suitability for downstream analyses.

    Main Methods:

    • The method integrates glass-bead column filtration, Ficoll-Hypaque density gradient, and discontinuous sucrose gradient centrifugation.
    • A significant reduction in the number of cell transfer steps was implemented.

    Main Results:

    • The procedure yields a high quantity of pure human lymphocytes.
    • The B cell/T cell ratio is well-preserved during the isolation process.
    • The isolated lymphocytes are suitable for subsequent biochemical studies.

    Conclusions:

    • This optimized method provides a reliable and efficient means of obtaining pure human lymphocytes.
    • The technique is advantageous for studies requiring high-purity cells and preserved cellular integrity.
