CD2是一种有用的早期T细胞系限制性抗原，存在于T细胞分化过程中。CD2染色作为一种泛T细胞标记物，几乎可以用来识别所有正常的T细胞，但在某些T细胞肿瘤中可能会被删除。由于CD2存在于大多数前体和成熟的T细胞白血病和淋巴瘤中，因此CD2在淋巴系统恶性肿瘤的评估中有很大的应用价值。CD2和CD25染色支持对系统性肥大细胞增多症和肥大细胞白血病的认识。

Cluster of differentiation 2 (CD2) is a useful early T-cell lineage restricted antigen that is present in T-cell differentiation. As a pan-T-cell marker, CD2 staining is used for recognizing practically all normal T-cells, but may be deleted in some T-cell neoplasms. Since CD2 is present in most precursor and mature T-cell leukemias and lymphomas, it is useful in the evaluation of lymphoid malignancies. By using CD2 and CD25 staining, the recognition of systemic mastocytosis and mastocytic leukemia is supported.
