General description

Runt-related transcription factor 1 (RUNX1), also known as Acute myeloid leukemia 1 protein, Core-binding factor subunit alpha-2 (CBF-alpha2), Oncogene AML-1, Polyomavirus enhancer-binding protein 2 alpha B subunit (PEA2-alpha B/PEBP2-alpha B), SL3-3 enhancer factor 1 alpha B subunit, and SL3/AKV core-binding factor alpha B subunit is encoded by the human gene named RUNX1/AML1, CBFA2. RUNX1 is a transcription factor that binds to a wide variety of promoters and enhancers belonging to many types of genes from T cell receptor genes to LCK, IL-3 and GM-CSF. Its major normal role is in the development of blood cells and hematopoiesis. It is expressed in most tissues except in normal brain and heart. Levels are highest in the bone marrow, thymus and peripheral lymphocytes. Defects and or translocations involving RUNX1 are the cause for myeloid leukemias as well as lymphoblastic leukemia. Mutations in RUNX1 function are also linked with many breast cancers. Finally, mutations in RUNX1 have recently been shown to be the cause of cancers in epithelial tissues and linked to squamous cell carcinomas. EMD-Millipore’s Anti-RUNX1 mouse monoclonal antibody has been tested in western blot on Jurkat cell lysates and in ELISA using recombinant RUNX1 protein.

Western Blotting Analysis: A 1:500-2,000 dilution of this antibody detected RUNX1 in Jurkat cell lysate.

Optimal working dilutions must be determined by end user.

Target description

~55 kDa observed. Uncharacterized bands may appear in some lysate(s).

Physical form

Mouse monoclonal IgG1 ascitic fluid containing up to 0.1% sodium azide.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
