Purpose:
- To evaluate the resolving power of the new
- Leitz MPV flow
- microscope-based flow cytometer for human karyotyping.
Summary:
- Human peripheral lymphocyte metaphase chromosomes were analyzed using the "Leitz MPV flow" cytometer.
- Simple ethidium bromide staining and mercury arc lamp excitation resolved the human karyotype into approximately 15 peaks.
- The results demonstrate the instrument's capability in flow cytogenetics.
Impact:
- The study highlights the potential of a cost-effective, microscope-based flow cytometer for advanced flow cytogenetic applications.
- This technology can compete with more sophisticated laser-based systems, making advanced analysis more accessible.
- It opens avenues for improved diagnostic tools in genetic research and clinical settings.
