CD61 also known as integrin beta chain beta 3 (ITGB3) is an integrin cell-surface protein associated with cellular adhesion and cell-surface mediated signaling. Immunohistochemical staining for CD61 can be useful in evaluating normal and abnormal megakaryocytes, which can aide in the identification of some hematopoietic malignancies. Anti-CD61 reactivity is also seen in platelets, osteoclasts and macrophages.

CD57, also known as HNK-1 (human natural killer-1), is a cell surface carbohydrate epitope expressed on terminally differentiated T-cells and subsets of natural killer (NK) cells.1 It has also been identified on cells of neural crest origin.2 Anti-CD57 is often used to visualize the non-neoplastic bystander T-cells that may form rosettes around the neoplastic lymphocyte-predominant (LP) cells in nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL).3

CD56, also known as neural cell adhesion molecule (NCAM), is a calcium-independent homophilic binding protein that belongs to a group of cell adhesion molecules including cadherins, selectins, and integrins. CD56 is involved in cellcell adhesion of neural cells during embryogenesis and is expressed on most neuroectodermally derived tissues. In normal tissue, anti-CD56 labels neurons, glia, schwann cells, NK (natural killer) cells, and a subset of T-cells.3 CD56 expression can be seen in most NK cell neoplasms, certain subtypes of T-cell lymphoma and in some plasma cell neoplasms. well

Anti-CD45RO labels an isoform of the CD45 antigen also known as leukocyte common antigen. Anti-CD45RO reacts with thymocytes, mature activated T-cells, and a subpopulation of resting T-cells while showing no reactivity with B-cells, making this antibody helpful in identifying T-cell neoplasms.

Anti-CD45 (anti-leukocyte common antigen) is routinely used to aid the differential diagnosis of undifferentiated neoplasms, whenever malignant lymphoma is suspected by the morphological or clinical data. It is a highly specific antibody; therefore a positive result is highly indicative of hematolymphoid origin. Certain types of hematolymphoid neoplasms may lack CD45 (Hodgkin lymphoma, some T-cell lymphomas, and some leukemias) so its absence does not rule out a hematolymphoid tumor. This antibody is expressed almost exclusively by cells of hematopoietic lineage and is present in most benign and malignant lymphocytes as well as plasma cell precursors.

The CD44 family of glycoproteins exists in a number of variant isoforms, the most common being the standard 85-95 kD or hematopoietic variant (CD44s) that is found in mesodermal cells such as hematopoietic, fibroblastic, and glial cells, as well as in some carcinoma cell lines. Higher molecular weight isoforms have been described in epithelial cells (CD44v) and are thought to function in intercellular adhesion and stromal binding. While many human tumors express CD44, a positive correlation between CD44v expression and tumor dedifferentiation has been demonstrated. MON 3237 may be useful in discrimination of urothelial carcinoma in-situ from non-neoplastic changes in the urothelium.

CD43 is a transmembrane protein involved in immune function and T-cell activation. AntiCD43 reactivity is seen in T lymphocytes, monocytes, and granulocytes. No reactivity has been observed in normal or reactive B-cells. Reportedly, anti-CD43 reactivity is seen in the majority of T-cell lymphomas and some low grade B-cell lymphomas. Therefore, anti-CD43 is a useful immunohistochemical marker for the identification of T-cell lymphomas and some low grade B-cell lymphomas

CD34 is a cell surface glycophosphoprotein expressed on human hematopoietic progenitor cells and can be used for identifying blast cells. CD34 is a marker for vascular endothelial cells and has been shown in literature to be highly sensitive for angiosarcomas and Kaposi's sarcomas. In addition, CD34 is expressed in soft tissue tumors such as gastrointestinal stromal tumors (GIST).

CD31 has cytoplasmic, membranous expression in non-neoplastic and neoplastic vascular endothelial cells.1 It has been used as a tool to identify the vascular origin of neoplasms such as angiosarcomas, Kaposi sarcomas and epithelioid hemangioendothelioma. Immunohistochemical study with CD31 has also been shown useful to detect areas of tumor lymphovascular invasion. Additionally, detection of weak diffuse cytoplasmic CD31 immunoreactivity has been seen in cases of various carcinomas with occasional membranous staining in ductal carcinomas of the breast as well as in intratumoral macrophages.

The antibody detects a formalin-resistant epitope that is expressed by Reed-Sternberg cells in classic Hodgkin lymphoma, the majority of anaplastic large cell lymphomas, primary cutaneous CD30 positive T-cell lymphoproliferative disorders and in embryonal carcinomas. Occasionally diffuse large B-cell lymphoma stains with this antibody. This antibody also stains plasma cells in paraffin-embedded tissue as well as reactive immunoblasts. The staining pattern of anti-CD30 in lymphoma and embryonal carcinoma is different, with the former being membranous and exhibiting Golgi zone accentuation in location, and the latter being membranous only.

CD25, Interleukin-2 receptor alpha chain, is the alpha subunit of the cell surface receptor which regulates regulatory T-cells. CD25 has been detected in various hematological malignancies including adult T-cell leukemia/lymphoma, and hairy cell leukemia. MON 3230 has also been useful in identifying mast cells in skin biopsies in the setting of Urticaria Pigmentosa, which is predictive of Systemic Mastocytosis.

CD23 antigen is a 45-60 kDa membrane glycoprotein identified as a low affinity receptor for IgE production as well as a receptor for lymphocyte growth factor. CD23 is found in some mature B-cell lymphomas and in Reed-Sternberg cells in Hodgkin disease. Follicular dendritic cells and some activated B-cells within germinal centers express CD23 in high density and mantle zone B-cells are stained. The majority of chronic lymphocytic leukemias/small lymphocytic lymphomas are anti-CD23 positive, whereas mantle cell lymphomas are generally negative, so this marker is useful when applied with other markers to separate the small cell lymphomas.1,3 Precursor B and T lymphomas, myeloid neoplasms, and mature T-cell lymphomas are CD23 negative and other small cell lymphomas are occasionally positive. Anti-CD23 is expressed in activated mature B-cells expressing IgM or IgD, monocytes/macrophages, follicular dendritic cells, T-cell subsets, eosinophils, Langerhans cells and small lymphocytic lymphoma/chronic lymphocytic leukemia.

CD21 (also known as complement receptor 2 (CR2), C3d receptor, or EBV receptor) is a 140 kDa membrane protein on B-lymphocytes to which the Epstein-Barr virus (EBV) binds during infection of these cells. The antigen is absent on T-lymphocytes, monocytes, and granulocytes. MON 3027 is useful in the identification of follicular dendritic cell matrix found in normal lymph node and tonsillar tissue. This antibody also labels follicular dendritic cell sarcomas. Anti-CD21 is valuable in differentiating follicular lymphoma with marginal zone differentiation from marginal zone lymphoma with follicular involvement. It also plays a role in distinguishing among nodular lymphocyte predominant Hodgkin lymphoma, lymphocyte-rich classic Hodgkin lymphoma, and T-cell/histiocyte-rich B-cell lymphoma in combination with other B-cell and T-cell markers.6 Anti-CD21 is also useful in identifying abnormal follicular dendritic cell pattern in angioimmunoblastic T-cell lymphoma and follicular T-cell lymphoma.
