آنتی بادیهای ایمونوهیستوشیمیآنتی بادی COX-2 (SP21)
Name: COX2 (Cyclooxygenase 2) Antibody (Clone SP21)
Description and applications: COX-2 (Cyclooxygenase-2) is an inducible enzyme. It is involved in the response of cells to growth factors, tumor promoters, and cytokines that induce its expression. Given its role in synthesizing prostaglandins, COX-2 is therefore of interest in studying immune response regulation. COX-2 is induced by a wide variety of stimuli and was initially identified as immediate-early growth response gene. In addition, COX-2 expression markedly increased in 85-90% of human colorectal adenocarcinoma whereas COX-1 levels remain unchanged. COX-2 is expressed in normal cells from mammary acini, uterine cervix, uterus, fallopian tubes, trophoblast of chorionic villi, prostate, seminal vesicles, epididymis, bladder urothelial epithelium, gastric glands or gallbladder. Consequently, COX-2 is expressed in many solid tumors. Intense to moderate cytoplasmic and sometimes membrane expression is observed in colorectal, prostate, cervical, endometrial, ovarian, urothelial, pancreatic and hepatic carcinomas. COX-2 is frequently expressed in breast carcinomas while up to 80% of pituitary adenomas are positive. The prognostic value of COX-2 expression is controversial.
Composition: anti-human COX2 rabbit monoclonal antibody purified by protein affinity and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.
Immunogen: Synthetic peptide corresponding to C-terminus of rat COX-2.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی INI1 (BAF47/SNF5) (25/BAF47)
Name: INI-1 (BAF47/SNF5) Antibody (Clone 25/BAF47)
Description and applications: SWI/SNF complexes facilitate gene activation and transcription factor binding by altering repressive chromatin structures in an ATP-dependent manner. In mammals, SWI/SNF complexes are present in mutliple forms that include 9-12 BRG1-associated factors (BAFs) per complex. These BAF proteins range in molecular weight from 47 to 250 kDa. BAF47/SNF5 (SMARCB1/Ini1) complexes with BRG1- and BRM-containing SWI/SNF complexes. BAF47/SNF5 mRNA is widely expressed in cell lines and tissues, and BAF47/SNF5 gene is mutated in many human tumors. The latter is indicative of a tumor suppressor role for BAF47/SNF5. In addition, mice deficient for BAF47 die early in embryogenesis, while BAF47/SNF5 heterozygous mice display a variety of tumors in the soft tissues of the head and neck. BAF47/SNF5 also binds the HIV-1 integrase and stimulates integrase-mediated DNA joining activity. Thus, BAF47/SNF5 is a component of SWI/SNF complexes that may be critical for normal development and tumor suppression, but may also be a protein utilized for viral DNA integration into host DNA. Expression in normal tissues is ubiquitous. In tumor tissue loss of protein expression SMARCB1 / INI1 gene was first observed in all malignant rhabdoid tumors of childhood of different location (soft tissue, kidney and CNS) and in medullary carcinomas of the kidney. Also loss of expression is observed in 50% of synovial sarcomas, some myxoid chondrosarcoma and myoepithelial carcinomas, almost all epithelioid sarcoma (proximal and conventional variants) and 50% of malignant tumors of peripheral nerves sheat, all presenting rhabdoid morphology. Loss of immunohistochemistry expression is also observed in cases of poorly differentiated chordoma. The antibody is useful in differentiating rhabdoid tumors of other tumors with similar morphology as desmoplastic round cell tumor, rhabdomyosarcoma and Wilms tumor do not show loss of expression of INI1. The antibody also is useful in confirming the diagnosis of medullary carcinoma and discard possible renal pelvis urothelial carcinoma or other carcinomas of the kidney showing expression for INI1. Maintained staining in most carcinomas, epithelioid angiosarcoma, mesotheliomas, melanomas and other tumors or lesions reagents (granulomas) of epithelioid morphology make this useful antibody in the diagnosis of epithelioid sarcoma.
Composition: anti-human INI-1 mouse monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.
Immunogen: mouse BAF47 aminoacids 257-359.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی Adipophilin (Polyclonal)
Name: Adipophilin Antibody (Polyclonal)
Description and applications: Sebaceous carcinoma is a relatively uncommon cutaneous malignancy and mimics other malignant neoplasms, such as basal and squamous cell carcinomas, and benign processes, such as chalazions and blepharitis, sometimes resulting in delayed diagnosis and suboptimal treatment. Adipophilin is present in milk fat globule membranes and on the surface of lipid droplets in various normal cell types. Recently, it has been reported that adipophilin was expressed in sebaceous adenomas with a specific pattern: membranous with strong uptake at the periphery of intracytoplasmic lipid vacuoles. Sebaceous carcinomas are also labeled with a similar pattern. Additionally, in cases of poorly differentiated sebaceous carcinoma, adipophilin highlights the sebocytes with a strong membranous labeling of intracytoplasmic lipid droplets. Moreover, xanthelasmas, xanthogranulomas, xanthomas, metastatic renal cell carcinomas were also weakly-to- moderately positive for adipophilin in one study. Expression of adipophilin with a membranous pattern of staining was not seen in any of the other clear cell lesions of the skin, including basal and squamous cell
carcinomas, trichilemmomas, clear cell hidradenomas,or balloon cell nevi. Interestingly, a nonspecific granular uptake of anti-adipophilin was seen in adjacent macrophages, keratohyalin granules of epithelial squamous cells, and some tumor cells.Therefore, this anti-adipophilin is suitable for immunostaining formalin-fixed, paraffin-embedded tissue and is helpful in the identification of intracytoplasmic lipids, as seen in sebaceous lesions. Acinary cell carcinomas of the breast, some liposarcomas, or carcinomas of the colon, lung, pancreas or prostate and strangely the majority of Burkitt lymphomas might also be positive.
Composition:Anti-human Adipophilin rabbit polyclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی Amyloid P (EP1018Y)
Name: Amyloid P Antibody clone EP1018Y
Description and applications: Serum Amyloid P (SAP) is a non-fibrillar plasma glycoprotein that belongs to the pentraxin family. It is universally found in amyloid deposits and this is probably due to its specific calcium-dependent binding to motifs present on all types of amyloid fibrils. SAP is also found to prevent fibrillar breakdown by enzymes and it is believed that it helps maintains stability of the amyloid deposits. It has been shown that SAP binds monocytes with high avidity, but does not bind to erythrocytes, NK cells, T lymphocytes or B lymphocytes. SAP production can be induced by exposure to IL-1, IL-6 and IFN-beta. The SAP-inducing activity was neutralized by antibodies to each of the recombinant cytokines. Recognition of these type of amyloid has prognostic and therapeutic implications. The increase in SAP secretion has been documented in different pathologies including neoplasms, rheumatoid arthritis
and CNS diseases. The synthesis of SAP is increased in systemic amyloidosis and is a common component in amyloid deposits. SAP has also been identified in arteriosclerotic lesions.Composition: Anti-human Amyloid P rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی ARG-1 (EP261)
Name: Arginase-1 Antibody (Clone EP261)
Description and applications: Arginase is a manganese metalloenzyme that catalyzes the hydrolysis of arginine to generate ornithine and urea. Arginiase I and II are isoenzymes which differ in subcellular localization, regulation, and possibly function. Arginase I is a cytosolic enzyme, which is expressed mainly in the liver as part of the urea cycle, whereas arginase II is a mitochondrial protein found in a variety of tissues. Antibody to ARG-1 labels hepatocytes in normal tissues and granulocytes in peripheral blood. ARG-1 is a sensitive and specific marker for identification of hepatocellular carcinoma. This antibody is very useful in distinguishing between: 1) liver metastases of various adenocarcinomas and hepatocellular carcinoma (HCC), which can be a realdiagnostic challenge, especially in small biopsies or material from fine needle aspiration ( FNA) and 2) the distinction between different histological variants of HCC and cholangiocarcinoma. Specifically, the ARG-1 antibody is key in the diagnosis of scirrhous hepatocellular carcinoma, where specific markers for adenocarcinomas are generally positive while HepPar-1 in some cases it may be negative. In addition, several studies have shown that ARG-1 antibody is more sensitive than HepPar-1 for immunohistochemical diagnosis of hepatocellular carcinoma while the second is usually negative in poorly differentiated hepatocellular carcinomas and can be positive in adenocarcinomas of pancreatic, gastric, colic origin or even cholangiocarcinoma. However, isolated cases of pancreatic adenocarcinomas and cholangiocarcinomas presented focal staining against ARG-1. In this line, it should be considered that the ARG-1 antibody does not allow differential diagnosis between benign, dysplastic and malignant hepatocyte lesions.
Composition: anti-human ARG-1 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی CD14 (EP128)
Name: CD14 Antibody (Clone EP128)
Description and applications:CD14 is a 55-kDa protein found as a glycosylphosphatidylinositol (GPI)- anchored protein on the surface of monocytes, macrophages, and polymorphonuclear leukocytes, and as a soluble protein in the blood. Its main function is to serve as a receptor for lipopolysaccharide (LPS). Besides its role in endotoxin signaling, it has been proposed that CD14 is involved in the transportation of other lipids, cell-cell interactions during different immune responses, and recognition of apoptotic cells.
CD14 is highly expressed on the surface of monocytes/macrophages and strongly up-regulated during the differentiation of monocytic precursor cells into mature monocytes. Therefore, CD14 has been commonly used as a differentiation marker for monocytes/macrophages. An antibody to CD14 also labels Langerhans cells and dendritic cells.Composition: Anti-human CD14 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی CD163 (EP324)
Name: CD163 Antibody (Clone EP324)
Description and aplications: CD163 was recently identified as an acute phase-regulated transmembrane protein whose function is to mediate the endocytosis of haptoglobin-hemoglobin complexes. This receptor is expressed on the surface of monocytes (low expression) and tissue macrophages [also known as histiocytes] (high expression). It is a member of the cysteine-rich scavenger receptor superfamily, encoded by a gene localized on human chromosome 12p13.3. Solubilized in plasma, CD163 functions as an anti-inflammatory signal and has many roles in disease processes that range from autoimmune conditions such as rheumatoid arthritis to atherosclerosis. Previous work has shown that the CD163 gene can be regulated by glucocorticoids, IL-10, and other inflammatory modulators, and is highly expressed in inflamed tissues, consistent with its role in the resolution of inflammation.
Staining for CD163 has been helpful in distinguishing synovial macrophages from synovial intimal fibroblasts in the setting of rheumatoid arthritis,where its specificity for macrophages was found to be superior to that of CD68, which does not discriminate between these cell types. Increased levels of CD163 were also detected in patients with microbial infections and myelomonocytic leukemias by an enzyme-linked immunosorbent assay. Flow cytometry studies have confirmed that CD163 expression is limited to leukemias with monocytic differentiation. Another recent study showed that all 5 cases of synovial-type giant cell tumors of the vertebral column stained for CD163.Composition: anti-human CD163 mouse monoclonal antibody obtained from supernatant. Prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.
