Transcription factor PU.1 is a protein that in humans is encoded by the SPI1 gene. The PU.1 transcription factor is essential for hematopoiesis and cell fate decisions. PU.1 can physically interact with a variety of regulatory factors like TFIID, GATA-2, GATA-1 and c-Jun. The protein-protein interactions between these factors can regulate PU.1-dependent cell fate decisions. PU.1 can modulate the expression of 3000 genes in hematopoietic cells including cytokines. It is expressed in monocytes, granulocytes, B and NK cells but is absent in T cells, reticulocytes and megakaryocytes. Its transcription is regulated by various mechanisms.
Flow cytometric analysis of 4% PFA fixed 90% methanol permeabilized HeLa (Human cervix adenocarcinoma epithelial cell, left) / U-937 (Human histiocytic lymphoma monocyte, Right) cells labelling PU.1 antibody at 1/500 dilution (0.1 μg) / (Red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody.
Negative control: HeLa
IHC shows positive staining in paraffin-embedded human stomach. Anti-PU.1 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human ovarian cancer. Anti-PU.1 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human diffuse large B-cell lymphoma. Anti-PU.1 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human mantle cell lymphoma. Anti-PU.1 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded classical Hodgkin lymphoma (Negative in R-S cells). Anti-PU.1 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
ICC shows positive staining in THP-1 cells. Anti-PU.1 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
