5B1 recognizes the human CD45 antigen, a tyrosine phosphatase also known as the leukocyte common antigen (LCA). The CD45 molecule is required for T and B cell activation and is expressed in at least five isoforms depending on the differentiation status of the cell. The CD45 antibody recognizes a common epitope of all CD45 isoforms.

BW264/56 recognizes the human CD3 antigen which is present on mature human T cells, thymocytes, and a subset of NK cells. CD3 is associated with the T cell receptor (TCR) and is responsible for its signal transduction. The CD3 antigen is a complex of five invariable chains: gamma, delta, epsilon, zeta and eta. The epitope recognized by the antibody is located on the epsilon-chain of the CD3 complex.

REA675 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. Additional information: Clone REA675 displays negligible binding to Fc receptors.

Clone REA671 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. CD38, a disease marker for human leukemias and myelomas, plays a role in the pathogenesis and outcome of human immunodeficiency virus infection and chronic lymphocytic leukemia, and controls insulin release and also the development of diabetes. Furthermore, it catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose which is essential for the regulation of intracellular Ca2+.
Additional information: Clone REA671 displays negligible binding to Fc receptors.

11F2 recognizes the human gamma/delta T cell receptor (TCR). The T cell receptor is a heterodimeric glycoprotein associated with the CD3 antigen. The TCR consists of a alpha and a beta chain (TCRa/b) or a gamma and a delta chain (TCRg/d). Clone 11F2 reacts with a framework epitope of the gamma/delta T cell–receptor. The gamma and delta TCR chains are composed of constant and variable regions, each encoded by distinct gene segments. The gamma chain forms either disulfide-linked or non-disulfide-linked heterodimers with the delta-subunit. The gamma/delta T cell–receptor is present on a subset of T lymphocytes in peripheral blood, intestinal epithelium, lymph node, thymus, and spleen. TCR gamma/delta is involved in the recognition of certain bacterial, self-CD1 molecule, and tumor antigens bound to MHC class I. Gamma/delta T cells are mainly CD4 negative and CD8 negative. T cells expressing the gamma/delta TCR have been shown to play a role in oral tolerance, innate immune response for some tumor cells, and autoimmune disease. Antigen presentation by gamma/delta T cells has been reported.

BW135/80 recognizes the human CD8 antigen which is strongly expressed on human cytotoxic T cells and thymocytes, and is also expressed on a subset of NK cells. The CD8 antigen is a disulfide-linked dimer that exists either as a CD8alpha homodimer or as a CD8alpha/beta heterodimer. CD8 acts as a coreceptor for the T cell receptor and binds to the MHC Class I molecule. The CD8 antibody recognizes the alpha-subunit of the antigen.

REA734 recognizes the human CD8 antigen, a cell-surface glycoprotein also known as Leu-2 or CD8a. CD8 is strongly expressed on human cytotoxic T cells and thymocytes as well as on a subset of NK cells. The CD8 antigen is a disulfide-linked dimer that exists either as a CD8a homodimer or as a CD8alpha/beta heterodimer. CD8 acts as a co-receptor for the T cell receptor and binds to the MHC class I molecules. CD8 is involved in T cell development and activation of mature T cells. The CD8 antibody recognizes the alpha-subunit of the antigen. Additional information: Clone REA734 displays negligible binding to Fc receptors.

REA747 recognizes the human CD45 antigen, a member of the protein tyrosine phosphatase (PTP) family, also known as the leukocyte common antigen (LCA). The CD45 molecule a type I transmembrane protein which is required for T and B cell activation and involved in cell growth, differentiation, mitotic cycle, and oncogenic transformation. CD45 is expressed in different isoforms (CD45RA, CD45RB, CD45RC, CD45RAB, CD45RAC, CD45RBC, CD45RO, CD45R (ABC)) depending on the differentiation status of the cell. The CD45 antibody recognizes a common epitope of all CD45 isoforms. Additional information: Clone REA747 displays negligible binding to Fc receptors.

AC136 recognizes the human CD34, a class III epitope of the CD34 antigen. This epitope is different than the one recognized by the clone used in the CD34 MicroBead Kits. The CD34 antigen is a single-chain transmembrane glycoprotein, expressed on human hematopoietic stem and progenitor cells, endothelial progenitor cells, vascular endothelial cells, embryonic fibroblasts, and some cells in fetal and adult nervous tissue. The antigen is absent on fully differentiated hematopoietic cells, such as normal peripheral blood lymphocytes, monocytes, granulocytes, erythrocytes, and platelets. Clone AC136 has a similar specificity as the CD34 monoclonal antibody clone 8G12 (HPCA-2). CD34 antibodies can be used for studies of hematopoiesis and nonhematopoietic stem cells, phenotyping of hematopoietic stem cells, and studies on phenotyping of hematologic malignancies, endothelial cells, and endothelial progenitor cells (EPCs).

T6D11 recognizes the human CD45RA antigen which is expressed on naive CD4+ and CD8+ T cells as well as on CD8+ effector T cells. CD45RA is also present on subsets of B and NK cells as well as on plasmacytoid dendritic cells. The CD45RA antibody recognizes the 220 kDa isoform of the leukocyte common antigen (LCA), a transmembrane tyrosine phosphatase.
