human ... NPM1(4869)


Nucleophosmin recombinant protein epitope signature tag (PrEST)


Anti-NPM1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

NPM1 (Nucleophosmin 1) is a nucleolar, multifunctional protein encoding a ubiquitously expressed nucleolar phoshoprotein. It is localized in the nucleolus. The protein moves from the nucleus as a molecular chaperone to the cytoplasm continuously. It is majorly involved in the cell proliferation and apoptosis. Mutation in the NPM1 gene causes a cytogenetical disorder, normal acute myeloid leukemia (CN-AML). Overexpression of NPM1 gene has been reported in several human cancerous cells, such as colon, ovarian, prostate, and gastric cancer. It has also been suggested that NPM1 may play a regulatory role in liver cancer.

Features and Benefits

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.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST70997.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Activation-induced cytidine deaminase (AID) is a DNA mutator enzyme essential for adaptive immunity. AID initiates somatic hypermutation and class switch recombination (CSR) by deaminating cytosine to uracil in specific immunoglobulin (Ig) gene regions. However, other loci, including cancer-related genes, are...
