LLC_x000D_ Biochem/physiol Actions_x000D_ GGH (γ-glutamyl hydrolase) is involved in the removal of γ-linked polyglutamates, thereby hydrolysing (anti)folylpoly-γ-glutamates. The enzyme controls the intracellular folate pools and folate metabolism. During the treatment of acute lymphoblastic leukemia (ALL), mutation in the GGH gene is linked with efficacy and side effects of methotrexate (MTX). It is responsible for changing a long-chain methotrexate polyglutamates (MTX-PGs) into a short-chain MTX-PGs and finally to MTX. Mutation in this gene at -401C>T enhances the response of cisplatin-based chemoradiotherapy in cervical carcinoma. The levels of GGH are higher in invasive breast cancer tumors and are associated with the development and progression of the cancer._x000D_ Features and Benefits_x000D_ Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST74642.
