Flow cytometric methods for the analysis of human basophil surface antigens and viability

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Background:

• Immunoglobulin E (IgE) plays a crucial role in allergic reactions and immune responses.
• Accurate detection and quantification of IgE-bearing cells, particularly basophils, are essential for immunological studies.
• Existing methods may have limitations in detecting IgE-bearing cells when they are present in low percentages.

Purpose of the Study:

• To establish fluorescence and flow microfluorometric methods for detecting and evaluating IgE-bearing human leukocytes.
• To develop quantitative techniques for assessing basophil purity, viability, and cell surface antigens.
• To facilitate the identification and phenotypic analysis of human IgE-bearing cells in diverse biological fluids.

Main Methods:

• Development and application of fluorescence-based assays.
• Utilization of flow microfluorometry for cell analysis.
• Quantitative assessment of cell surface markers, including IgE.

Main Results:

• Established reliable methods for detecting and evaluating IgE-bearing human leukocytes.
• Developed quantitative techniques applicable even when basophils are at low percentages.
• Demonstrated the capability to determine basophil purity, viability, and IgE expression.

Conclusions:

• The developed fluorescence and flow microfluorometric methods are effective for identifying and analyzing IgE-bearing human leukocytes.
• These techniques provide valuable tools for immunological research involving basophils and other IgE-expressing cells.
• The methods facilitate comprehensive phenotypic analysis in various biological samples.
