Human Activated T Cell Markers Flow Cytometry Panel #23428
Product Information
Protocol
Product Description
The Human Activated T Cell Markers Flow Cytometry Panel can be used to identify activated human T cells.
T cells are identified by expression of CD3. There are two major subsets of conventional T cells: helper T cells which express CD4, and cytotoxic T cells which express CD8. Upon stimulation through the T cell receptor, T cells upregulate expression of CD69 and IL-2Rα/CD25. Regulatory T cells constitutively express IL-2Rα/CD25.

Product Usage Information
All antibodies in this kit are compatible with the Flow Cytometry, Live Cell Protocol for Directly Conjugated Antibodies and can be used in a single staining mix. After antibody staining and prior to acquisition on a flow cytometer, we recommend adding Propidium Iodide or 7-AAD to enable identification and exclusion of dead cells from the analysis.
Gating strategy for identifying activated T cells:
If Propidium Iodide or 7-AAD was used, first gate on viable cells. Next, gate on lymphocytes based on forward scatter and side scatter. Helper T cells are the CD3+CD4+ cells within the lymphocyte gate. Activated helper T cells are positive for expression of CD69 and/or IL-2Rα/CD25. Regulatory T cells can also express IL-2Rα/CD25. Cytotoxic T cells are the CD3+CD8+ cells within the lymphocyte gate. Activated cytotoxic T cells are positive for expression of CD69 and/or IL-2Rα/CD25.

Specificity / Sensitivity
Each antibody in the Human Activated T Cell Markers Flow Cytometry Panel detects endogenous levels of its target protein. CD3 (UCHT1) Mouse mAb (PE Conjugate), CD4 (RPA-T4) Mouse mAb (violetFluor™ 450 Conjugate), CD8α (RPA-T8) Mouse mAb (FITC Conjugate), IL2-Rα/CD25 (BC96) Mouse mAb (APC Conjugate), and CD69 (FN50) Mouse mAb (PE-Cy7® Conjugate) detect epitopes within the extracellular domains.
Species Reactivity:
Human
Source / Purification
Monoclonal antibodies were purified from tissue culture supernatant via affinity chromatography. The purified antibodies were conjugated under optimal conditions, with unreacted dye removed from the preparation.
