Clone REA340 recognizes the human CD22 antigen, a single-pass type I membrane protein which is also known as sialic acid-binding Ig-like lectin 2 (Siglec-2). In peripheral blood, cell surface expression of CD22 is found on mature B cells, but is lost during terminal differentiation to plasma cells. In bone marrow, surface expression of CD22 can be detected from the pre–B cell stage on. Cytoplasmic expression of CD22 can also be found in late pro–B cells and early–B cells. CD22 plays a strong role in cell interactions and B cell activation. It is a regulatory molecule that prevents the overactivation of the immune system and the development of autoimmune diseases. CD22 has emerged as an ideal target for monoclonal antibody based therapy of B cell malignancies including most lymphomas and many leukemias. Additional information: Clone REA340 displays negligible binding to Fc receptors.

BW242/412 recognizes the human alpha/beta T cell receptor (TCR). The T cell receptor (TCR) is a heterodimer composed of two transmembrane glycoprotein chains, alpha and beta. Both chains are members of the Ig superfamily and consist of a constant and a polymorphic variable region. The variable region of the TCRa/b is involved in recognition of antigenic peptides presented by the MHC complex of antigen-presenting cells. The Anti-TCRa/b antibody, BW242/412, recognizes a common determinant of the TCRa/b-CD3 complex.

4E3 recognizes the human CD25 antigen, a 55 kDa glycoprotein also known as the low-affinity interleukin-2 receptor alpha chain (IL-2Rα). CD25 is expressed on activated T and B cells, on macrophages, and on a subset of non-activated CD4+ regulatory T cells. The CD25 antigen contains three epitope regions called A, B, and C. This CD25 antibody recognizes epitope region B.

REA414 recognizes the human CD66c antigen, a glycosylphosphatidylinositol (GPI) linked protein, which is also known as carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6). Within the hematopoietic system, CD66c expression is limited to granulocytes and its precursors, where it serves homotypic and heterotypic adhesion, Ca2+ mediated signaling, and is markedly upregulated from intracellular stores after activation. It is also found in epithelia of various organs. CD66c overexpression is found in a wide variety of epithelial cancer types such as lung, breast, colorectal, and hepatocellular carcinomas.
Additional information: Clone REA414 displays negligible binding to Fc receptors.

The monoclonal antibody UP-H2 reacts with human CD300e, also known as IREM-2, LMIR6, or CMRF35-A5. This 34 kDa activating receptor of the immunoglobulin superfamily is expressed on mature myeloid dendritic cells and monocytes and is down-regulated on immature dendritic cells. CD300e interacts with DAP-12, which mediates activating signals. It is reported that the alloreactive response of naive T cells is enhanced by IREM-2 activation of mDCs.

REA613 recognizes the human CD3 antigen, a single-pass type I membrane protein, also known as Leu4. CD3 is present on mature human T cells, thymocytes, a subset of NK cells, and on Purkinje cells in cerebellum. It 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. Additional information: Clone REA613 displays negligible binding to Fc receptors.

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.

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.

Clone REA423 recognizes the human CD16 antigen, a single-pass type I membrane protein which is also known as low affinity immunoglobulin gamma Fc region receptor III (FcRIII). CD16 is a 50–80 kDa glycoprotein that is expressed in two different isoforms. The transmembrane form is found on human NK cells, macrophages, and mast cells, while the glycosylphosphatidylinositol (GPI)-linked form is present on neutrophils. The human CD16 antigen is a low-affinity receptor for aggregated IgG. The transmembrane form plays a role in signal transduction, NK cell activation, and antibody-dependent cellular cytotoxicity. Clone REA423 recognizes both the extracellular domain of the transmembrane form as well as the GPI-linked form of the human CD16 antigen. CD16 is expressed on the majority of rhesus monkey NK cells and on a subset of monocytes but not on granulocytes. Additional information: Clone REA423 displays negligible binding to Fc receptors.
