Flow cytometry, combined with monoclonal antibodies, offers powerful methods for assessing leukocyte function. This technique analyzes cell surface markers and early activation events, aiding in disease diagnosis and understanding immune responses.

Area of Science:

  • Immunology
  • Cell Biology
  • Clinical Research

Background:

  • Monoclonal antibody technology and flow cytometry are essential tools for leukocyte characterization.
  • Flow cytometry is widely used for immunophenotyping lymphocytes in leukemias and immunodeficiency disorders.

Purpose of the Study:

  • To review the diverse applications of flow cytometry in assessing leukocyte function.
  • To highlight how cell surface antigen analysis provides insights into cell function and activation states.

Main Methods:

  • Utilizing monoclonal antibodies for immunofluorescence identification of cell surface markers.
  • Analyzing activation antigen expression to identify functional leukocyte populations.
  • Quantitatively measuring lymphocyte subset proliferation and early activation events via flow cytometry.
