CD34 [QBEnd/10]
Description CD34 (Cluster of differentiation 34) is a single-pass type I transmembrane glycoprotein which primary functions as a cell to cell adhesion factor. As an adhesion factor, CD34 is expressed during stem/progenitor stage of lymphohematopoietic development and possibly mediates the stem cell attachment to the bone marrow, ECM or stromal cells. CD34 is expressed on hematopoietic stem/progenitor cells, endothelial cells, fibroblasts and other stromal components. CD34 is an important marker for quantifying and purifying hematopoietic progenitor/stem cells. It is useful in identification of tumors with endothelial or lymphoid differentiation. In addition, CD34 aids in detection of gastrointestinal stromal tumors.

CD36 [MD172]
Description Recognizes a protein of 80kDa-90kDa, identified as CD36. It is expressed on platelets, monocytes and macrophages, microvascular endothelial cells, erythrocyte precursors, mammary epithelial cells, and some macrophage derived dendritic cells. CD36 acts as a receptor for thrombospondin (TSP), collagen types I, IV and V, P. falciparum malaria-infected erythrocytes, and sickle erythrocytes. It also functions as a scavenger receptor, mediating macrophage uptake of oxidized low-density lipoprotein (LDL) and recognition of apoptotic polymorphonuclear leukocytes (PMN). CD36 plays a role in platelet aggregation, macrophage foam cell development, inflammation, and the tissue ischemia observed in sickle cell disease and cerebral malaria. Note that 1-4% of Japanese and East Asia population lack CD36.

CD4 [MT310]
Description CD4 is a glycoprotein found on the surface of immune cells such as T helper cells, monocytes, macrophages and dendritic cells. It is a co-receptor that assists the T-cell receptor (TCR) with an antigen-presenting cell and also interacts directly with MHC class Ⅱ molecules on the surface of the antigen-presenting cells using its extracellular domain. In lymphatic tissues, the CD4+ T-cells are seen in large numbers in the parafollicular zone, while scattered cells are found in the germinal centres and mantle zone. CD4 is also demonstrated in hepatic sinusoidal cells, monocytes and monocytes-derived cells but not expressed on B-cells and immature thymocytes. Precursor T-lymphoblastic lymphomas are therefore variable in their expression of CD4. Most mature T-cell lymphomas are CD4 positive with the exception of aggressive NK-cell leukemia and extranodal NK/T-cell lymphoma. CD4 plays an important role in the classification of lymphocytes in inflammatory lesions and malignant lymphomas.

CD42a [A9]
Description The CD42a antibody recognizes a 17 to 22-kilodalton (kDa) single-chain, platelet membrane glycoprotein, also known as gpIX that forms a noncovalent complex with gpIb and gpV. Glycoprotein Ib consists of an α–chain disulfide-linked to a β chain. Glycoproteins Ibα (140 to 145 kDa), Ibβ (24 to 25 kDa), and V (82 to 86 kDa) have been designated as CD42b, CD42c and CD42d respectively. CD42a has been reported to react with both gpIX and the gpIb-IX-V complex.

CD42b [42C01]
Description The CD42b glycoprotein, also known as GPIb, is a co-factor of ristocetin-induced aggregation and is involved in the binding of platelets to blood vessel walls. The CD42b antigen is expressed on platelets and on megakaryocytes in bone marrow. The absence of CD42b antigen on platelets may indicate Bernard-Soulier disease. CD42b is a platelet activation marker involved in the process of coagulation as an aggregating factor. It interacts with extracellular matrix as well as with adhesion molecules. Its expression and activation seems to be regulated by VEGF and PDGF.

CD44 (HCAM) [156-3C11]
Description CD44 is a cell-surface glycoprotein postulated to play a role in a variety of biological processes, including cell-to-cell and cell-to-matrix adhesion, lymphocyte homing and tumor cell metastasis. Several isoforms of CD44 have been identified in human cells, and the genesis of some of these isoforms has been attributed to alternative splicing. Understanding of mechanisms regulating CD44 alternative splicing may provide insights into diverse processes, including tumor-cell metastasis and lymphocyte homing. CD44 is widely expressed on many types of cells with mesodermal and hematopoietic origin, epithelial cells and a variety of tumors derived from these cells. Loss of CD44 expression has been linked to tumor invasion, metastasis and progression in carcinomas of breast, prostate, lung, ovary and malignant melanoma. Expressed on approximately 90% of lymphocytes, monocytes, granulocytes, and, in lower amounts on thymocytes, fibroblasts, and erythrocytes.

CD47/IAP (Integrin Associated Protein) [CD47/2937]
Description This antibody reacts with Ig domain of CD47 protein. It has been shown to inhibit polymorphonuclear neutrophil (PMN) transmigration across cell monolayers and matrix. CD47, originally named integrin-associated protein (IAP), is a 50kDa protein containing five membrane-spanning sequences and a short cytoplasmic tail. CD47 plays a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. It is important in memory formation and synaptic plasticity in the hippocampus. CD47 may play a role in membrane transport and/or integrin dependent signal transduction.
