High quality products to support Pathologists and Biological and Environmental Scientists
GeneAb™ CD56
$50.00 – $160.00Cluster of Differentiation 56 (CD56), also known as Neural-Cell Adhesion Molecule (NCAM), is a glycoprotein involved in synaptic plasticity, cell-cell adhesion, neurite outgrowth, learning, and memory. NCAM is expressed in normal neurons, glia, natural killer cells, activated T-cells, brain and cerebellum, neuroendocrine tissues, and skeletal muscle. Anti-CD56 recognizes a number of tumours including myeloma, myeloid leukemia, natural killer/T-cell lymphomas, neuroendocrine tumours, pancreatic acinar-cell carcinoma, pheochromocytoma, and Wilm’s tumour. CD56 is detectable in neoplasms that are neuroectodermally-derived, such as retinoblastoma, medulloblastomas, astrocytomas, small cell carcinomas, and neuroblastomas. It has also been linked to rhabdomyosarcoma, a tumour that is mesodermally-derived.
GeneAb™ p57 kip2
$115.00 – $860.00p57Kip2, also known as p57, is a tumour suppressor protein that causes cell cycle arrest at G1 by binding to G1 cyclin-CDK complexes. The p57Kip2 gene is a potential tumour suppressor target as the gene is located in a chromosomal region implicated in sporadic cancers, Wilms’ tumour, and Beckwith Wiedemann syndrome. Anti-p57Kip2 labels many cytotrophoblast nuclei and stromal cells in normal placenta, and is useful in differentiating between complete hydatidiform mole and partial hydatidiform mole or hydropic abortion.
GeneAb™ p40
$145.00 – $560.00Anti-p40 recognizes squamous and basal cells, the shortest variant of p53, and ΔNp63 (an isoform of p63). p40 has been indicated as an alternative to p63 for the detection of Squamous Cell Carcinoma (SqCC), offering the advantage of eliminating potential misinterpretation of a positive adenocarcinoma as a SqCC.
GeneAb™ CD61
$125.00 – $665.00Cluster of Differentiation 61 (CD61), also known as Glycoprotein IIIa or GPIIIa, is an antigen expressed on megakaryocytes, platelets, myeloid cells, monocytes, endothelial cells, smooth muscle cells, and macrophages. It is involved in platelet aggregation and acts as a receptor for fibrinogen, fibronectin, von Willebrand factor, and vitronectin. Anti-CD61 is used for identifying megakaryocytopoiesis, as seen in megakaryoblastic leukemias, myelodysplastic disorders, and acute myeloid leukemias. CD61 is also indicated as a marker for platelet adhesion in advanced atherosclerosis and has been reported in the identification of fat embolism in pulmonary tissue.
GeneAb™ CD68
$80.00 – $305.00Cluster of Differentiation 68 (CD68) is a heavily glycosylated transmembrane antigen that is detected in lysosomes, tissue macrophages, Langerhans cells, dendritic cells, monocytes, Kupffer cells, osteoclasts, and granulocytes. Anti-CD68 may be useful in identifying myelomonocytic and histiocytic tumours, and for differentiating between malignant fibrous histiocytoma and other pleomorphic sarcomas. However, other lysosome-rich cells may also stain, since Anti-CD68 detects a formalin-resistant epitope that may be associated with lysosomal granules.
GeneAb™ CD71
$75.00 – $340.00Cluster of Differentiation 71 (CD71), also known as Transferrin Receptor Protein 1 (TfR1) or the transferrin receptor, is a cell surface proliferation marker that is involved in the cellular uptake of iron. CD71 is most highly expressed in early erythroid precursors and is fully absent from mature erythrocytes; CD71 is therefore highly useful as a marker for erythroid components within bone marrow biopsy specimens, without interference from mature erythrocytes. CD71 expression has been indicated in invasive breast carcinoma with acquired resistance to tamoxifen, and has been linked to poor prognosis in ER+/luminal-like breast cancer. Anti-CD71 is used in the determination of erythroid leukemia, benign erythroid proliferative disorders, and myelodysplastic syndrome.
GeneAb™ CD73
$225.00 – $880.00Cluster of Differentiation 73 (CD73), also known as Ecto-5′-Nucleotidase (ecto-5′-NT), is a cell surface enzyme found in most tissues. CD73 catalyzes the breakdown of AMP to adenosine, thereby modulating inflammatory and T-cell responses. Reports have implicated CD73 expression in tumour progression and carcinogenesis, as CD73 is a key regulatory molecule in the proliferation, migration, and invasion of cancer cells in vitro, as well as tumour angiogenesis and tumour immune escape in vivo. Due to this key involvement in cancer, CD73 has become an appealing target for cancer immunotherapy. CD73 expression has also been linked to favourable prognosis in breast carcinoma.
GeneAb™ Desmoglein-3
$125.00 – $570.00Desmoglein-3 Antibody (DSG3) is a component of desmosomes in vertebrate epithelial cells. It identifies pulmonary squamous cell carcinomas from other types of lung cancer with high specificity and sensitivity. Studies show the upregulation of DSG3 correlated with metastasis in a number of cancers including lung cancers. The expression of DSG3 indicates a poor prognosis and portends a more aggressive clinical outcome.
