[A method of determining subpopulations of B-lymphocytes using a flow cytometer]

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Context:

• Accurate enumeration of human B-lymphocyte subpopulations is crucial for diagnosing and monitoring various immunological disorders.
• Traditional methods like fluorescent microscopy can be labor-intensive and subjective.
• There is a need for more efficient and objective techniques for B-cell analysis.

Purpose:

• To develop and validate a novel flow cytometry method for quantifying human B-lymphocyte subpopulations.
• To utilize monospecific porcine antisera targeting FITC-labeled human immunoglobulins for B-cell identification.
• To compare the efficacy of the developed flow cytometry method against traditional fluorescent microscopy.

Summary:

• A flow cytometry protocol was established using monospecific porcine antisera and FITC-labeled human immunoglobulins to measure human B-lymphocyte subsets.
• The method demonstrated high correlation with results obtained from conventional fluorescent microscopy.
• This indicates the reliability and accuracy of the flow cytometry approach for B-cell enumeration.

Impact:

• Provides a validated, high-throughput method for B-lymphocyte subpopulation analysis.
• Offers a potentially more objective and efficient alternative to traditional B-cell measurement techniques.
• Facilitates advancements in immunological research and clinical diagnostics through improved B-cell quantification.
