This antibody recognizes a 67kDa transmembrane protein, which is identified as CD5. It is found on 95% of thymocytes and 72% of peripheral blood lymphocytes. In lymph nodes, the main reactivity is observed in Tcell areas. CD5 antibody is a pan Tcell marker that also reacts with a range of neoplastic Bcells, e.g. chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma, and a subset (~10%) of diffuse large Bcell lymphoma. Aberrant expression is useful in making a diagnosis of mature Tcell neoplasms. CD5 antibody detection is diagnostic in CLL/SLL within a panel of other Bcell markers, especially one that includes anti-CD23. CD5 antibody is also very useful in differentiating among mature small lymphoid cell malignancies. In addition, it can be used in distinguishing thymic carcinoma (+) from thymoma (-). It does not react with granulocytes or monocytes.

Application Notes

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the CD5 antibody to be titered up or down for optimal performance.


Stimulated human leukocytes were used as the immunogen for this CD5 antibody.


Store the CD5 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
