Protocols
- 3542:
- IHC / Paraffin, Western Blotting
Specificity / Sensitivity
NPM Antibody detects endogenous levels of total NPM protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the amino-terminus of human NPM. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from SW-13, NIH/3T3, Jurkat and PC12 cells, using NPM Antibody.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human breast carcinoma, showing nuclear localization, using NMP Antibody.
IHC-P (paraffin)
Im munohistochemical analysis of paraffin-embedded human colon carcinoma, using NPM Antibody in the presence of control peptide (left) or antigen-specific peptide (right).
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human lung carcinoma, using NPM Antibody.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human metastatic adenocarcinoma, in lymph node, using NPM Antibody.
Background
Nucleophosmin (NPM; also known as B23, numatrin or NO38) is an abundant phosphoprotein primarily found in nucleoli. It has been implicated in several distinct cellular functions, including assembly and transport of ribosomes, cytoplasmic/nuclear trafficking, regulation of DNA polymerase α activity, centrosome duplication and molecular chaperoning activities (1,2). The NPM gene is also known for its fusion with the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase. The NPM portion contributes to transformation by providing a dimerization domain, which results in activation of the fused kinase (3,4).
