C3-reacted sepharose: a preparative method for separating T and B lymphocytes.

P Casali, B M Perussia

    Clinical and Experimental Immunology
    |January 1, 1977
    PubMed
    Summary

    Researchers developed a method to isolate lymphocytes with complement receptors (CR+) using C3-Sepharose columns. This technique allows for the purification of specific immune cells for further study.

    Area of Science:

    • Immunology
    • Cell Biology

    Background:

    • Complement receptors (CR) play a crucial role in immune responses.
    • Isolating specific lymphocyte populations is essential for understanding immune function.

    Purpose of the Study:

    • To describe a novel method for separating lymphocytes bearing complement receptors (CR+).
    • To evaluate the specificity and efficiency of the described separation technique.

    Main Methods:

    • Utilized C3-reacted Sepharose columns as solid-phase immunoabsorbents for cell separation.
    • Employed elution with an IgG fraction from rabbit antiserum to human C3 for recovering CR+ lymphocytes.

    Main Results:

    • Successfully separated lymphocytes expressing complement receptors from mixed cell suspensions.
    • Demonstrated the specificity of the immunoabsorbent method for CR+ cells.
    • Reported on the yields of purified CR+ lymphocytes obtained.

    Conclusions:

    • The described method provides an effective means for isolating CR+ lymphocytes.
    • This technique enhances the ability to study complement receptor-bearing cells in immunological research.
