7 18 because of its ubiquity on all b cells it can function as a b cell marker and a target for immunotherapies targeting neoplastic lymphocytes. Shearer wt et al. Cd20 is a protein that is expressed on the surface of b cells starting at the pre b cell stage and also on mature b cells in the bone marrow and in the periphery. Cd20 is not expressed on hematopoietic stem cells pro b cells or normal plasma cells 1 plasmablasts and stimulated plasma cells may express cd20 2 cd20 is generally coexpressed on b cells with cd19 another b cell differentiation marker.

The result and loinc information listed below should not be used for electronic interface maintenance with quest diagnostics. Cd19 expression is even maintained in b lineage cells that undergo neoplastic transformation.

The percentages of b cells were evaluated with the expression of cd10 cd19 and cd20. Wbcs are stained with fluorescently labeled monoclonal antibodies to cd14 cd19 cd20 and cd45 and run on a flow cytometer and the cd19 and cd20 antigen expression are analyzed. The cd19 antigen plays an important role in clinical oncology. Cd20 is not expressed on hematopoietic stem cells pro b cells or normal plasma cells 1 plasmablasts and stimulated plasma cells may express cd20 2 cd20 is generally coexpressed on b cells with cd19 another b cell.

The distribution of these b cell subsets reference ranges based on gender is shown in table 3. It s a protein found on the surface of b cells a type of white blood cell. Pediatric normal range chart.
