    Animal complement sources do not affect human B lymphocyte detection. Using different animal sera interchangeably is reliable for preparing zymosan-C3 complexes to identify B cells.

    Area of Science:

    • Immunology
    • Cell Biology

    Background:

    • Accurate detection of human B lymphocytes is crucial for immunological studies.
    • Complement sources can influence immunological assays.
    • Zymosan-C3 complexes are used for B lymphocyte identification.

    Purpose of the Study:

    • To evaluate the impact of different animal serum complement sources on the preparation of zymosan-C3 complexes.
    • To determine if human B lymphocytes can differentiate between complement C3 from various animal species.

    Main Methods:

    • Preparation of zymosan-C3 complexes using sera from five different animal species.
    • Quantification of zymosan-C3 (ZC) rosette-forming cells to assess B lymphocyte percentage.
    • Comparative analysis of B cell detection across different complement sources.

    Main Results:

    • No significant variation was observed in the percentage of ZC rosette-forming cells when using complement from different animal species.
    • Human B lymphocytes did not exhibit discrimination based on the animal origin of the complement C3.
    • Interchangeable use of various animal complement sources did not alter B cell detection rates.

    Conclusions:

    • The choice of animal serum as a complement source does not impact the accuracy of human B lymphocyte detection via zymosan-C3 complex assay.
    • This finding supports the flexibility and interchangeability of different animal complement sources in this specific immunological method.
    • The study validates the robustness of the zymosan-C3 rosette assay for B cell enumeration regardless of complement origin.
