High quality products to support Pathologists and Biological and Environmental Scientists
GeneAb™ LMO2
$110.00 – $500.00LMO2, also known as LIM-Only transcription factor 2, RBTN2, or TTG2, is an oncoprotein that is expressed in normal germinal center B-cells, as well as bone marrow hematopoietic precursors and endothelial cells. LMO2 plays a role in angiogenesis and hematopoesis, and its expression has been detected in erythroid and myeloid precursors, megakaryocytes, and also in lymphoblastic and acute myeloid leukemias. LMO2 protein expression has been noted in diffuse large B-cell lymphoma, the most common adult non-Hodgkin lymphoma, as well as follicular lymphoma, a neoplasm derived from germinal center B-cells that accounts for a number of cases of non-Hodgkin lymphomas.
GeneAb™ Ki-67
$75.00 – $340.00Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
GeneAb™ KBA.62 (Melanoma Associated Antigen)
$100.00 – $370.00KBA.62, also known as Melanoma Associated Antigen, is used to detect an antigen present in melanocytic tumors, such as melanomas, due to its proven sensitivity and specificity. The antibody can also be used to distinguish between junctional nevus and intradermal nevus cells, and fetal melanocytes versus normal adult melanocytes. Studies have shown KBA.62 to be highly useful in differentiating between metastatic amelanotic melanoma and a number of poorly differentiated carcinomas, large cell lymphomas, sarcomas, and spindle cell carcinomas.
GeneAb™ Kappa
$35.00 – $140.00Anti-Kappa recognizes surface immunoglobulin on normal and neoplastic B-cells, and has been indicated as a potential aid in the identification of leukemias, plasmacytomas, and certain non-Hodgkin’s lymphomas, where the expression of a single light chain class is restricted. The determination of light chain ratio is critical in evaluating B-cell neoplasms, as the majority of B-cell lymphomas express either kappa or lambda light chains, while a mixture of kappa and lambda is characteristic of reactive proliferations. In paraffin-embedded tissue, Anti-Kappa displays strong staining of kappa-positive plasma cells, as well as cells that have absorbed exogenous immunoglobulins.
GeneAb™ IDH1 R132H
$140.00 – $545.00Isocitrate Dehydrogenase 1 (IDH1) is a soluble, cytosolic enzyme involved in the TCA metabolic cycle. The most notable mutation in this enzyme, R132H, is clinically indicated in the majority of astrocytomas and oligodendroglial tumours, with the mutation being associated with more favourable prognosis and increased survival in those patients. IDH1 R132H is also useful in the differential diagnosis between anaplastic glioma and glioblastoma.
GeneAb™ HER2/neu
$90.00 – $450.00The Her2/Neu (c-erbB-2) proto-oncogene is a transmembrane receptor tyrosine kinase that is clinically indicated in a number of carcinomas. Overexpression of the c-erbB-2 protein has been associated with ductal breast cancer, as well as pulmonary and gastric adenocarcinomas. A correlation between Her2 and p53 has also been documented, as overexpression of both proteins has been associated with early invasion and metastasis in bladder cancer.
GeneAb™ Hairy Cell Leukemia
$150.00 – $680.00Anti-Hairy Cell Leukemia stains various B-cells in the follicular mantle zone and virtually all cases of hairy cell leukemia. It also stains some high grade B-cell lymphomas.
GeneAb™ GATA3
$120.00 – $595.00GATA3 is a transcription factor important in cell proliferation, development, and differentiation. GATA3 is mostly observed in breast and urothelial carcinomas, and rarely present in other cancers such as endometrial endometrioid adenocarcinoma. Among the breast carcinomas, GATA3 has a lower expression in luminal B subtype breast carcinoma. Studies have found GATA3 expression to be associated with ER (estrogen receptor), PR (progesterone receptor), and Her2 in breast cancer cases. Urothelial carcinomas stain positively for GATA3 in invasive or high grade tumors, therefore Anti-GATA3 is useful for carcinoma diagnosis when breast and bladder are plausible.
