Western Blot (WB)
(Nucleophosmin antibody (pAb) tested by Western blot. Nuclear extract of Jurkat cells (30 ug per lane) probed with Nucleophosmin antibody (pAb) at a dilution of 1:1,000.)
Rabbit anti-Human Nucleophosmin Polyclonal Antibody | anti-NPM1 antibody
Nucleophosmin antibody (pAb)
WB: 1:500-1:2,000 dilution
Note: Many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt/Sonication Protocol when preparing nuclear extracts for Western blot.

Background: Nucleophosmin (NPM, NPM1, Nucleolar phosphoprotein B23) is a highly phosphorylated nucleolar protein involved in ribosome biogenesis, maintenance of genome stability, is directly implicated in cancer pathogenesis and serves as a histone chaperone. Nucleophosmin is closely related to Nucleoplasmin and shuttles back and forth between the nucleolus and the nucleoplasm. Chromosomal aberrations involving Nucleophosmin were found in patients with non-Hodgkin lymphoma, acute promyelocytic leukemia, myelodysplastic syndrome, and acute myelogenous leukemia. Nucleophosmin has been shown to interact with Nucleolin, AKT1, BRCA1 and BARD1. Mice deficient for Nucleophosmin have severe defects in genome stability due to unrestricted centrosome duplication. Heterozygous Nucleophosmin mutant mice show signs of myelodysplastic syndrome.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is involved in several cellular processes, including centrosome duplication, protein chaperoning, and cell proliferation. The encoded phosphoprotein shuttles between the nucleolus, nucleus, and cytoplasm, chaperoning ribosomal proteins and core histones from the nucleus to the cytoplasm. This protein is also known to sequester the tumor suppressor ARF in the nucleolus, protecting it from degradation until it is needed. Mutations in this gene are associated with acute myeloid leukemia. Dozens of pseudogenes of this gene have been identified. [provided by RefSeq, Aug 2017]
Uniprot Description
NPM1: a nucleolar protein associated with nucleolar ribonucleoprotein structures and that binds single-stranded nucleic acids. Is a major component of template activating factor (TAF)-III. It plays a role in controlling centrosome duplication, and may function in the assembly and/or transport of the ribosome. Two alternatively spliced isoforms have been described.

Product Notes
The NPM1 npm1 (Catalog #AAA388606) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Nucleophosmin antibody (pAb) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Nucleophosmin can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Applications Validated: WB: 1:500-1:2,000 dilution Note: Many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt/Sonication Protocol when preparing nuclear extracts for Western blot. Researchers should empirically determine the suitability of the NPM1 npm1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Nucleophosmin, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
