What is Immunophenotyping?
Immunophenotyping is a laboratory technique used to analyze the types of cells in a sample based on the presence or absence of specific surface markers, which are typically proteins expressed on the cell membrane. This process is commonly applied in immunology and hematology to characterize and classify immune cells, such as lymphocytes, and to diagnose various diseases, including leukemias, lymphomas, and other hematological disorders.
The technique often involves the use of monoclonal antibodies that are specific to particular cell surface markers. These antibodies can be tagged with fluorescent dyes or other labels, allowing for the detection and quantification of the cells expressing those markers through flow cytometry or other imaging techniques. By analyzing the patterns of marker expression, clinicians can determine the cell lineage, activation status, and overall health of the immune cells in the sample.
Immunophenotyping is critical in clinical settings for:
1. Diagnosing and classifying blood cancers (e.g., leukemia, lymphoma).
2. Monitoring disease progression and response to treatment.
3. Researching immune system function and cellular interactions.
Overall, immunophenotyping provides valuable insights into the cellular composition of blood and other tissues, aiding in both diagnosis and therapeutic decision-making.
