Area of Science:

  • Immunology
  • Veterinary Medicine
  • Cell Biology

Background:

  • Flow cytometry gating is crucial for analyzing cell subpopulations and accurate diagnosis.
  • Standard human lymphocyte gating uses CD45 and CD14 markers, which are not universally available across species.
  • Veterinary research often relies on limited lymphocyte surface antigens like CD4, CD8, and T-lymphocyte markers.

Purpose of the Study:

  • To develop and describe a standardized flow cytometry gating technique for lymphocyte identification applicable across species.
  • To address the challenge of limited marker availability in veterinary flow cytometry.
  • To enhance the accuracy of cell subpopulation quantification in veterinary clinical cases.

Main Methods:

  • A novel gating strategy was developed using a T-lymphocyte antibody.

Related Experiment Videos

  • The technique was designed for applicability across various species with limited phenotype markers.
  • Standard flow cytometry procedures were employed for cell analysis.

    • Main Results:

    • A standardized gating technique using T-lymphocyte antibodies was successfully described.
    • The method is shown to be applicable across species where limited phenotype markers are available.
    • This technique facilitates the selection of lymphocyte populations free from debris and unrelated cells.

    Conclusions:

    • The described standardized gating technique provides a reliable method for lymphocyte identification in veterinary flow cytometry.
    • This approach overcomes limitations of marker availability, enabling more accurate diagnoses.
    • The technique is broadly applicable, enhancing cross-species cell analysis in research and clinical settings.
