ALK-1 (for heme cases) The ALK1 (ALK1 cline) antibody labels normal human ALK protein and the NPM-ALK chimeric protein, and is a useful tool for the identification of the subgroup of anaplastic large-cell lymphomas (ALCL)…
Immunohistochemistry (IHC)
B-Cell Gene Rearrangement Detection of clonal IgH gene rearragements by PCR of IgH framework regions 1, 2, 3 and joining regions. In addition, Ig Kappa gene rearrangement analysis is performed using specific oligonucleotides…

BOB1 BOB1 is present in all B-cells expressing Ig. The combination of BOB1 and OCT2 staining is helpful in distinguishing between classical Hodgkin lymphoma (at least one marker negative) and nodular…
Immunohistochemistry (IHC)
CD15 CD15 (X-Hapten) plays a role in mediating phagocytosis, bactericidal activity, and chemotaxis. It is present on granulocytes, including neutrophils and eosinophils, and to a lesser degree on…
Immunohistochemistry (IHC)
CD20 Normal cell expression of CD20 is found on most B-cells (after CD19 and CD10 expression, before CD21/22 expression and surface immunoglobulin expression) and expression is retained on mature B-cells…
Immunohistochemistry (IHC)
CD3 The CD3 antigen is first detectable in early thymocytes and its appearance probably represents one of the earliest signs of commitment to the T-cell lineage. It has a cytoplasmic expression at early…
Immunohistochemistry (IHC)
CD30 CD30 is a lymphocyte activation antigen, related to tumor necrosis factor. It is expressed in activated B-, T- and NK cells. Positive staining is seen in infectious mononucleosis, lymphocytes…
Immunohistochemistry (IHC)
CD45 (LCA) CD45 (Leukocyte Common Antigen, LCA) is comprised of at least four isoforms (CD45RA, CD45RB, CD45RC and CD45RO) of membrane glycoproteins. CD45 is expressed on hematopoietic cells (human leukocytes,…
Immunohistochemistry (IHC)
CD79a CD79a first appears at the pre B-cell stage and persists until the plasma cell stage where it is found as an intracellular component. CD79a is found in the majority of acute leukemias of precursor B-…
Immunohistochemistry (IHC)
EBER This probe set labels all latent EBV-infected cells, including EBV-positive lymphoblastoid cell lines and EBV infected B-cell immunoblasts in infectious mononucleosis. It also reacts with EBV-…
In Situ Hybridization (ISH)
Fascin Human fascin is a highly conserved actin-bundling protein. It is expressed predominantly in dendritic cells. Lymphoid cells, myeloid cells and plasma cells are negative for staining. However, Reed-…
Immunohistochemistry (IHC)
Ki67 Ki67 is a nuclear protein that is expressed in proliferating cells. Ki67 is preferentially expressed during late G1, S, M, and G2 phases of the cell cycle, while cells in the G0 (quiescent) phase are…
Immunohistochemistry (IHC)
OCT2 Octamer Binding Transcription Factor 2 (OCT2) is present in all B-cells expressing Ig. The combination of BOB1 and OCT2 stains is helpful in distinguishing between classical Hodgkin lymphoma (at…
Immunohistochemistry (IHC)
PAX5 Paired Box 5 (PAX5) is a B-cell specific activator protein (BSAP). In early stages of B-cell development, PAX5 influences the expression of several B-cell specific genes, such as CD19 and CD20. PAX5…
Immunohistochemistry (IHC)
