Immunophenotyping
Seeing the Immune System Clearly
Every immune cell carries a unique signature. Flow cytometry is a powerful application to analyze those signatures, identifying and characterizing cell populations with a precision that has changed how we understand, diagnose, and treat disease. From hematologic malignancies to HIV monitoring to the expanding frontier of cell therapy, immunophenotyping sits at the center of some of the most important work happening in medicine today. Getting it right each time starts with controlling process variability.


Why Immunophenotyping Matters
Immune cell profiling guides the diagnosis of leukemias and lymphomas, informs treatment decisions in HIV care and supports monitoring in transplant and immunotherapy programs. As cell therapy continues to advance, accurately characterizing complex cell populations becomes even more critical. The stakes are high — and uncertainty about results is not an option.

Where Quality Control Makes the Difference
Flow cytometry generates rich, complex data. That complexity is powerful but can also create quality control challenges when developing a new panel or running one routinely.
- Marker coverage
Keeping pace with expanding panel
size and complexity. - Longitudinal consistency
Ensuring comparable results across runs,
operators and instruments. - Normal and abnormal populations
Distinguishing true biological variation
from process or instrument errors.

Controls Built for Clarity Amidst Complexity
Flow cytometry panels are becoming larger and more complex, and quality control must keep pace. Streck’s flow cytometry controls span a broad range of markers across normal and abnormal cell populations, enabling laboratories to verify performance across everything they test — not just a subset. That comprehensive coverage supports consistent, reliable immunophenotyping across instruments, operators and time. That’s The Science of Trust®.
