A simple immunoenzyme batch staining method for the enumeration of peripheral human T lymphocyte subsets

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Background:

• Accurate enumeration of human T lymphocyte subsets is crucial for immunological studies and clinical diagnostics.
• Existing methods for T cell subset analysis can be complex or require fresh cell preparations.

Purpose of the Study:

• To develop a simple batch method for enumerating peripheral human T lymphocyte subsets.
• To validate the accuracy of the new method by comparing it to established techniques.

Main Methods:

• Development of a batch immunoenzyme staining protocol for stored, prefixed peripheral mononuclear cells.
• Utilized multiple well microscope slides for simultaneous staining.
• Employed monoclonal antibodies Leu 1, Leu 2a, and Leu 3a for T cell subset identification.
• Comparison with indirect immunofluorescence staining on suspended cells.

Main Results:

• The developed batch immunoenzyme staining method successfully enumerated peripheral human T lymphocyte subsets.
• Staining results for Leu 1, Leu 2a, and Leu 3a positive cells were comparable to those obtained by indirect immunofluorescence on suspended cells.
• The method allows for the analysis of stored, prefixed cell preparations.

Conclusions:

• A simple and effective batch method for T lymphocyte subset enumeration has been established.
• This technique offers a viable alternative to indirect immunofluorescence, particularly for analyzing stored cell samples.
• The immunoenzyme staining approach provides accurate quantification of T cell subsets, facilitating immunological research.
