7C6B05_PURE_SPI1-PU1_Antibody_1_WB_070918
Total cell lysates (15 µg protein) from THP1 (lane 1) and MCF-7 (lane 2) cells were resolved by electrophoresis (4-20% Tris-Glycine gel), transferred to nitrocellulose, and probed with 1:1000 diluted (0.5 µg/mL) Purified anti-SPI1 (PU.1) Antibody, clone 7C6B05 (upper panel). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated with HRP for anti-SPI1 (PU.1) Antibody or 1:4000 Direct-Blot™ HRP anti-GAPDH antibody, clone W17079A (lower panel) as a loading control.

    THP-1 cells were stained with purified anti-PU.1 (clone 7C6B05) antibody, followed by staining with DyLight™ 488 conjugated goat anti-mouse IgG (green) antibody. Nuclei were stained with DAPI (blue).
  • 7C6B05_PURE_SPI1-PU1_Antibody_3_IP_070918
    Immunoprecipitation of PU.1 from THP-1 cell extracts. Lane 1 is 5% input. Immunoprecipitation was performed using protein G resins only (lane 2), mouse IgG isotype control (lane 3), and anti-PU.1 antibody (clone 7C6B05, lane 4). Western blot was performed using anti-PU.1 antibody (clone 7C6B05). The astrostar indicates immunoglobulin heavy chain and light chain.

Description

SPI1 is a transcription factor belonging to the E26-transformation-specific (Ets) family and is exclusively expressed in hematopoietic cells. SPI1 regulates cell fate decisions during differentiation of hematopoietic stem cells, which is crucial for the development of lymphoid and myeloid cell lineages. SPI1-deficient mice lack macrophages, neutrophils, and B lymphocytes, and they die before or shortly after birth. Abnormally regulated expression of SPI1 can lead to developmental defects as well as occurring malignancy. Overexpression of SPI1 blocks erythroid differentiation and inhibits cell death.  Mice carrying a mutant SPI1 allele show decreased SPI1 expression and develop acute myeloid leukaemia (AML), suggesting the role of SPI1 in oncogenesis.
