GFAP [GA-5]
Description Glial fibrillary acidic protein (GFAP) is the subunit of the glial specific “intermediate” filament that include desmin filaments in smooth muscle, vimentin filaments in cultured fibroblasts, keratin filaments in epithelium and neurofilaments in neural cells. GFAP is a major product of astrocytic differentiation. Compared with special stains currently used to identify an astroglial component in brain tumors, GFAP staining is more sensitive. Further, the immunohistochemical staining method is useful in demonstrating reactive astrocytes, whether secondary to a brain tumor or to any other neuro-pathological condition.

GGT1 [E5]
Description Glutamyltransferase (GGT) from human kidney is a membrane-bound enzyme that transfers the gamma-glutamly moiety of gamma-glutamyl compounds such as glutathione to an acceptor, which may be an amino acid or a di- or tripeptide or water. The principal functions of gGT may be hydrolysis and metabolism of glutathione. Various human gGT isoforms have been found. The molecular mass of gGT for normal kidney is 90kDa and gGT can be used as a renal cell marker.

GLG1 (Golgi Glycoprotein 1) [GLG1/970]
Description This antibody recognizes a protein of 134kDa, which binds fibroblast growth factor and E-selectin (cell-adhesion lectin on endothelial cells mediating the binding of neutrophils). Fucosylation is essential for binding to E-selectin. It contains sialic acid residues and 16 Cys-rich GLG1 repeats. This antibody can be used to stain the Golgi complex in cell or tissue preparations and can be used as a Golgi marker in subcellular fractions. It produces a diffuse staining pattern of the Golgi zone in normal and malignant cells. This antibody is an excellent marker for human cells in xenographic model research. It reacts specifically with human cells. The Golgi apparatus is an organelle present in all eukaryotic cells that forms a part of the endomembrane system. The primary function of the Golgi apparatus is to process and package macromolecules synthesized by the cell for exocytosis or use within the cell. The Golgi is made up of a stack of flattened, membrane-bound sacs known as cisternae, Host Mouse Application Flow cytometry (FC), Immunocytochemistry (ICC),Immunofluorescence (IF), Immunohistochemistry (IHC), Western Blot (WB) Reactivity Human -
Glutamine Synthetase [GS-6]
Description Glutamine synthetase, an enzyme that catalyzes the amination of glutamic acid to form glutamine, is found in mammals as an octamer of eight identical 45 kDa subunits. Glutamine synthetase activity has been shown to be a useful marker of astrocytes and an important differentiation feature in retina. Glutamine synthetase is also present in hepatocytes near the hepatic central veins. In liver focal nodular hyperplasia (FNH), the glutamine synthetase immunohistochemical staining pattern appears map-like, which is useful in differentiating FNH from normal liver tissue or other hepatic mass lesions.

Granzyme B [GZMB/3014]
Description Granzyme B is a member of the granule serine protease family stored specifically in NK cells or cytotoxic T cells. Cytolytic T lymphocytes (CTL) and natural killer (NK) cells share the ability to recognize, bind, and lyse specific target cells. They are thought to protect their host by lysing cells bearing on their surface 'nonself' antigens, usually peptides or proteins resulting from infection by intracellular pathogens. Granzyme B is crucial for the rapid induction of target cell apoptosis by CTLs in the cell-mediated immune response. Granzyme B is useful as a marker in the identification of T/NK-cell lymphomas in conjunction with CD56 (Shipping Cost: €200.00) Host Mouse Application Immunohistochemistry (IHC) Reactivity Human -
Growth Hormone (HGH) [GH/1450]
Description Growth hormone (GH or hGH), also known as somatotropin or somatropin, is a peptide hormone that is produced and secreted by somatotrophs of the anterior pituitary gland. GH exerts a wide variety of biological actions in many different tissues and cell types. The actions of GH at the cellular level can be divided into three categories: those affecting mitogenesis, differentiation, and metabolism. The GH antibody specifically labels somatotrophs in pituitary in normal tissues. It is useful in classification of pituitary tumor.

Hairy Cell Leukemia [DBA.44]
Description Hairy cell leukemia (HCL) is a rare type of chronic lymphoid leukemia. The disease is characterized by abnormal white blood cells bearing hair-like projections from the cytoplasm. These cancerous cells are larger than normal and positive for CD19, CD20, CD22, CD11c, CD25, CD103 and FMC7. HCL commonly causes infection, anemia and/or easy bleeding in patients. Some of the leukemic cells may gather in the spleen and cause it to swell, leading to massive splenomegaly. Patients with a high tumor burden may also have significantly reduced levels of cholesterol. There are two variants of hairy cell leukemia: hairy cell leukemia-variant, which is usually diagnosed in older men; and a Japanese variant. HCL markers are important research tools as they allow for the functional and behavioral analysis of this type of leukemia. DBA.44, a B subset antibody, reacts with very few normal cells. 50-97% of HCL cases are positive; about 35% of low grade B-cell lymphomas are positive; and about 30-80% of s Host Mouse Application Immunohistochemistry (IHC) Reactivity Human
