NPM1 Antibody (NPM1/3286) Summary

Recombinant human NPM1 protein fragment (aa185-287) (exact sequence is proprietary)
Nuclear, Cytoplasmic
This antibody recognizes a 33kDa glycoprotein, identified as Nucleophosmin (NPM1). It is predominantly localized in the nucleus of cells in most tissues. NPM1 is involved in ribosomal assembly and rRNA transport. It is an abundant protein that is highly phosphorylated by Cdc2 kinase during mitosis. This phosphoprotein moves between the nucleus and the cytoplasm. It is thought to be involved in several processes including regulation of the ARF/p53 pathway. A number of genes are fusion partners, in particular the anaplastic lymphoma kinase gene on chromosome 2. Mutations in exon 12 affecting the C-terminus of the protein are associated with an aberrant cytoplasmic location. Mutations in this gene are associated with acute myeloid leukemia. The antibody may be a useful aid for classification of acute myeloid leukemia.

  • ELISA 2-4 ug/ml
  • Flow Cytometry 1-2 ug/million cells
  • Immunocytochemistry/Immunofluorescence 1-2 ug/ml
  • Immunohistochemistry 1-2 ug/ml
  • Immunohistochemistry-Paraffin 1-2 ug/ml
  • Protein Array
  • Western Blot 1-2 ug/ml
Application Notes
ELISA: Use Ab at 2-4ug/ml for coating. Order Ab without BSA.
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
Theoretical MW
33 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
