HB5 recognizes CD21, a type I membrane glycoprotein. Expression of CD21 in humans is found on B cells, follicular dendritic cells, subsets of epithelial cells, and thymic T cells. The primary function attributed to CD21 has been to amplify the B cell receptor (BCR)-mediated signal transduction in response to antigen recognition. To enhance the BCR mediated activation, CD21 associates with CD19 and CD81 in a B cell–specific signal transduction complex, where interaction of BCR with CR2/CD19 amplifies the signals. In addition, CD21 serves as a receptor for split products of complement protein C3, the gp350/220 viral coat protein of the EBV and the immunoregulatory protein CD23.

145/15 recognizes the human CD62L antigen, a 74 kDa glycoprotein and a member of the selectin family of cell surface molecules. CD62L is also known as L-selectin, LECAM-1, or LAM-1 and binds a series of glycoproteins including CD34, GlyCAM-1, and MAdCAM-1. CD62L is important for homing of naive lymphocytes via endothelial venules to peripheral lymph nodes and Peyer’s patches. The CD62L antigen also contributes to the recruitment of leukocytes from the blood to areas of inflammation. Most hematopoietic cells express CD62L, including many peripheral blood B cells, T cells, monocytes, granulocytes, and some myeloid cells from bone marrow, and thymocytes. CD62L is continuously endoproteolytically cleaved from the cell surface neutrophils and lymphocytes (shedding). Proteolysis is accelerated, for example, after antigenic activation of T cells. Always use fresh material for immunofluorescent staining of CD62L+ cells. For optimal results, the cells should not be older than 8–12 hours. Keep cells continuously cold. CD62L-expression may be rapidly lost due to shedding.

Expression of CD42a is found on platelets and megakaryocytes. CD42a, together with GPIb receptor complex and platelet glycoprotein V forms a complex which serves as the receptor for von Willebrand factor (VWF). The interaction of the GPIb-IX-V complex to VWF initiates initial platelet adhesion to vascular subendothelium after vascular injury, platelet activation, thrombosis, and hemostasis. Other known ligands for GPIb–IX–V include α-thrombin, clotting factors XI/XIIa, and high-molecular weight kininogen. Additional information: Clone REA209 displays negligible binding to Fc receptors.

The GP Ib receptor complex further includes association of the alpha and beta subunits with platelet glycoprotein IX and glycoprotein V and this complex serves as the receptor for von Willebrand factor (VWF). The interaction of the GP Ib-IX-V complex to VWF initiates initial platelet adhesion to vascular subendothelium after vascular injury, platelet activation, thrombosis, and hemostasis.

REA113 recognizes CD94, an approximately 45 kDa, single pass, type II transmembr
REA113 recognizes CD94, an approximately 45 kDa, single pass, type II transmembrane protein, which belongs to C-type lectin superfamily. CD94 associates covalently with NKG2 family members and forms disulfide-bonded heterodimers. CD94-NKG2 receptors bind HLA-E, the non-classical MHC class Ib molecule. Depending on the associated NKG2 member, CD94-NKG2 heterodimer transmits either activating or inhibitory signal. For example, via immunoreceptor tyrosine–based inhibitory motifs (ITIMs) containing NKG2A, CD94-NKG2A heterodimers inhibit NK cell cytotoxicity. Besides NK cells, expression of CD94-NKG2 heterodimers is also shown on NK-T cells and a small percentage of CD8 cells in mice, where the crosslinking of CD94-NKG2 was shown to reduce the level of spontaneous apoptosis. Additional Information: Clone REA113 displays negligible binding to Fc receptors.

REA108 recognizes human CD197 which is a chemokine receptor with a C-C motif that mediates homing of T cells to secondary lymphoid organs via high endothelial venules (HEV) and is also known as CCR7. For example, naive T cells migrate very efficiently through lymph nodes using the adhesion molecules L-selectin, CD62L, and CCR7. Ligands for CCR7, e.g. CCL19, are expressed by the HEV of secondary lymphoid organs, by parenchymal cells within T cell zones of lymph nodes, and by endothelial cells at the openings of lymphatic vessels within peripheral tissues. Expression of CCR7 and the CD45RA isoform distinguishes three subsets of T cells: naive T cells (CCR7+CD45RA+), central memory T cells (CCR7+ CD45RA-), and effector memory T cells (CCR7- CD45RA-).
Clone FR3-16A11 recognizes CD203c, a glycosylated type II transmembrane molecule
Clone FR3-16A11 recognizes CD203c, a glycosylated type II transmembrane molecule that belongs to the family of ecto-nucleotide pyrophosphatase/ phosphodiesterase (E-NPP3) enzymes. Among hematopoietic cells, expression of CD203c is restricted to basophils as well as to mast cells and their precursors, and has been described as specific for this lineage. Protein and/or mRNA expression of CD203c has also been found in solid tissues such as uterus or prostate. Basophils and mast cells are key producers of mediators that drive the onset of inflammatory responses, e.g., in allergy. Allergen challenge leads to a rapid up-regulation of activation markers such as CD203c or CD63. Due to its restricted expression pattern, CD203c is discussed as a specific marker to monitor the allergen-induced activation of basophils, e.g., in flow cytometric basophil activation tests of the peripheral blood.

VIT4 recognizes the human CD4 antigen which is highly expressed on human T helper cells and thymocytes, and at lower levels on monocytes and dendritic cells. It is responsible for the recognition of the MHC Class II antigen.
HB5 recognizes CD21, a type I membrane glycoprotein. Expression of CD21 in human
HB5 recognizes CD21, a type I membrane glycoprotein. Expression of CD21 in humans is found on B cells, follicular dendritic cells, subsets of epithelial cells, and thymic T cells. The primary function attributed to CD21 has been to amplify the B cell receptor (BCR)-mediated signal transduction in response to antigen recognition. To enhance the BCR mediated activation, CD21 associates with CD19 and CD81 in a B cell–specific signal transduction complex, where interaction of BCR with CR2/CD19 amplifies the signals. In addition, CD21 serves as a receptor for split products of complement protein C3, the gp350/220 viral coat protein of the EBV and the immunoregulatory protein CD23.
IB6 recognizes the human CD38 antigen, a single-chain type II transmembrane glyc
IB6 recognizes the human CD38 antigen, a single-chain type II transmembrane glycoprotein with enzymatic activity. It is present on the majority of hematopoietic cells, prevalent during early differentiation and activation processes. Terminally differentiated B cells (plasma cells) express CD38 brightly. Furthermore, CD38 is constitutively expressed in several tissues, for example brain, muscle, and kidney.
AC145 recognizes human CD123, also known as IL-3 receptor alpha-chain. It is the
AC145 recognizes human CD123, also known as IL-3 receptor alpha-chain. It is the primary low-affinity subunit of the IL-3 receptor. CD123 associates with CD131, the common beta-chain of the IL-3, IL-5, and GM-CSF receptor, to form the high-affinity IL-3 receptor. The IL-3 receptor is involved in cell signaling for cell growth and differentiation. In peripheral blood, the CD123 antigen is expressed at high levels only on plasmacytoid dendritic cells and basophilic granulocytes but at low levels also on monocytes, eosinophilic granulocytes, myeloid dendritic cells, and subsets of hematopoietic progenitor cells.
LT19 recognizes the human CD19 antigen, a type-I transmembrane glycoprotein of 9
LT19 recognizes the human CD19 antigen, a type-I transmembrane glycoprotein of 95 kDa that belongs to the immunoglobulin superfamily. CD19 is expressed on B cells throughout most stages of B cell differentiation, though its expression is down-regulated during their terminal differentiation to plasma cells. Expression of CD19 is also found in the majority of B cell–derived malignancies. CD19 is further present on follicular dendritic cells. On B cells, CD19 associates with CD21, CD81, and CD225 (Leu-13) forming a signal transduction complex.
