Activation of the classical complement pathway by BioRex-70.

R J Vandenberg, S B Easterbrook-Smith

    Immunology Letters
    |January 1, 1987
    PubMed
    Summary

    The cation exchange resin BioRex-70 activates the classical complement pathway in human serum. This immune response activation proceeds to complement protein C3, even at low resin concentrations.

    Area of Science:

    • Immunology
    • Biochemistry
    • Materials Science

    Background:

    • The complement system is a crucial part of innate immunity.
    • Understanding activators of the complement system is vital for immunological research.
    • Cation exchange resins are widely used in various biochemical applications.

    Purpose of the Study:

    • To investigate the potential of the cation exchange resin BioRex-70 to activate the classical complement pathway.
    • To determine the extent of complement activation induced by BioRex-70.

    Main Methods:

    • Incubation of human serum with varying concentrations (0-5% v/v) of BioRex-70 at 37°C.
    • Utilizing zymosan-treated human serum to assess complement activation.
    • Quantifying complement activation by measuring the formation of complement protein C3.

    Main Results:

    • BioRex-70 demonstrated the ability to activate the classical complement pathway in human serum.
    • Activation was observed across the tested resin concentration range.
    • The activation process was confirmed to proceed up to the level of complement protein C3.

    Conclusions:

    • The cation exchange resin BioRex-70 serves as an activator of the classical complement pathway.
    • BioRex-70 can induce complement activation in human serum, reaching the C3 protein level.
    • These findings suggest potential applications or implications of BioRex-70 in immunological studies or related fields.
