Immunofluorescent analysis of Nucleophosmin (green) showing staining in the nucleus of MCF-7 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Nucleophosmin monoclonal antibody (Product # MA5-12508) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4°C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. Actin was stained using Alexa Fluor 554 (red) and nuclei were stained with Hoechst or DAPI (blue). Images were taken at a magnification of 60x.

MA5-12508 targets Nucleophosmin in IHC (P), ICC/IF and WB applications and shows reactivity with human and mouse samples.
The MA5-12508 immunogen is gST fusion protein containing the N-terminal part of nucleophosmin fused to 14 aa of ALK protein.
Nucleophosmin (NPM)/B23/numatrin is a phosphoprotein associated with cell nucleoli. Treatment of cells with cytotoxic drugs may make nucleophosmin enter nucleoplasm. It is reported that nucleophosmin shuttles continuously between cytoplasm and nucleoli to carry newly synthesized ribosomal proteins into nucleoli. NPM-ALK is a hybrid of the anaplastic lymphoma kinase (ALK) gene and the nucleophosmin (NPM) gene resulting from the t(2;5)(p23;q35) translocation found in anaplastic large cell lymphoma. In acute promyelocytic leukemia NPM gene is fused to RARalpha gene in (5;17) (q33;q12) transition.
