Applications

Western Blot Validated

Application Notes

Applications Validated by Active Motif:
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.

Immunogen

This Nucleophosmin antibody was raised against a peptide within the C-terminal region of human nucleophosmin.

Buffer

Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

 

Nucleophosmin antibody (pAb) tested by Western blot.
Nuclear extract of Jurkat cells (30 µg per lane) probed with Nucleophosmin antibody (pAb) at a dilution of 1:1,000.

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.

Storage
