What cell type is indicated by the CD20 marker?

The CD20 marker is primarily associated with B cells. This cell surface protein is commonly used as a pan-B-cell marker and is significant in the identification and isolation of B lymphocytes in various applications, especially in flow cytometry and immunophenotyping. CD20 plays a crucial role in B cell activation and proliferation, making it a valuable target for certain therapies, particularly in the treatment of B cell malignancies such as non-Hodgkin lymphoma. Understanding the specificity of CD20 aids practitioners in diagnosing and treating conditions related to B cells effectively.
