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 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 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 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.

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.

REA196 recognizes the human CD56 antigen, a glycoprotein of the Ig-superfamily, also known as neural cell adhesion molecule (NCAM), which is expressed in blood on practically all resting and activated NK cells and on a minor subset of CD3+ T cells. CD56 is also expressed in brain (cerebellum and cortex) and at neuromuscular junctions. Certain large granular lymphocyte (LGL) leukemias, small-cell lung carcinomas, neuronal-derived tumors, myelomas, and myeloid leukemias also express CD56.
Additional information: Clone REA196 displays negligible binding to Fc receptors.

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.
