    Experimental Notes
    The nucleophosmin antibody ABIN1737584 reveals a protein of the expected molecular weight in lysates of OCI-AML3 and of HEK-293T transfected with GFP-NPM mutA. The protein band is but not visible in the HL-60 negative control. A weak band from OCI-AML3 detected by an anti-NPMwt antibody confirms the concurrent presence of both NPMmutA and NPMwt in the OCI-AML3 cell line.

    Background
    Nucleophosmin (NPM) is a multi-functional protein that is involved in many cellular activities including cell growth, proliferation and transformation. It is frequently overexpressed in solid tumors, and has recently been found to be mutated and aberrantly localized in the cytoplasm of leukaemic blasts in patients with acute myeloid leukemia (AML).
