A specific antibody for cells with acquired B antigen

R Herron, D Young, M Clark

    Transfusion
    |November 1, 1982
    PubMed
    Summary

    Researchers investigated an acquired B antigen on red blood cells. They identified a specific antibody that detects this antigen, distinct from normal B cell reactions.

    Area of Science:

    • Immunology
    • Transfusion Medicine
    • Hematology

    Background:

    • Acquired B antigen is a rare phenomenon observed in some individuals.
    • It can cause discrepancies in blood typing, potentially leading to transfusion complications.

    Purpose of the Study:

    • To investigate the serological characteristics of an acquired B antigen.
    • To identify and characterize the antibody responsible for detecting the acquired B antigen.

    Main Methods:

    • Blood typing using anti-B sera.
    • Separation and characterization of antibodies from typing sera.
    • Production of specific antibodies in rabbits through immunization.

    Main Results:

    • A weak acquired B antigen was detected on donor red blood cells.

  • A separable antibody specific for the acquired B antigen was isolated.
  • This specific antibody did not react with normal group B red blood cells.
  • A similar specific antibody was successfully produced in a rabbit.

    • Conclusions:

    • The acquired B antigen can be specifically detected by a distinct antibody.
    • Understanding these antibodies is crucial for accurate blood transfusion practices.
    • Further research into the immunobiology of acquired B antigens is warranted.
