Area of Science:

  • Immunology
  • Biotechnology
  • Cell Biology

Background:

  • Flow cytometry is a valuable research and diagnostic tool, increasingly popular due to advancements in monoclonal antibodies.
  • High equipment and reagent costs limit the widespread adoption of flow cytometry.
  • Current protocols often recommend fixed reagent amounts, regardless of target cell numbers, especially in lysed whole blood techniques.

Purpose of the Study:

  • To investigate if an individualized reagent concentration, based on the actual number of mononuclear cells (MNCs), can maintain satisfactory results while reducing costs.
  • To assess the feasibility of cost reduction in flow cytometry through optimized reagent usage.

Main Methods:

  • Studied four groups: 259 healthy subjects (239 blood donors, 20 volunteers) and 10 HIV+ patients.
  • Investigated the impact of adjusting monoclonal antibody (MAB) and MNC concentrations.
  • Compared results using standardized versus individualized reagent volumes.

Main Results:

  • Results suggest that lower reagent amounts can be used in routine flow cytometry analysis.
  • Following provider instructions for reagent concentration (e.g., 1 µL MAB/1 x 10^5 MNCs) can yield satisfactory outcomes.
  • Potential for significant cost reduction in diagnostic and research settings.

Conclusions:

  • Individualized reagent concentration based on MNC count is a viable strategy for cost-effective flow cytometry.
  • Routine cytometric analyses can be performed with reduced reagent volumes without compromising qualitative results.
  • This approach can make flow cytometry more accessible and affordable for broader applications.
