Background
BMI-1 (B-cell-specific Moloney murine leukemia virus integration site 1) is a critical polycomb group protein that functions as an essential component of the Polycomb Repressive Complex 1 (PRC1), playing a pivotal role in epigenetic gene silencing by catalyzing the monoubiquitination of histone H2A at lysine 119, thereby repressing key target genes such as the INK4a/ARF locus (which encodes tumor suppressors p16INK4a and p14ARF) to regulate cell cycle progression, cellular senescence, and stem cell self-renewal; beyond its normal physiological functions in development and hematopoiesis, BMI-1 is frequently overexpressed in various malignancies, where it drives tumorigenesis, promotes cancer stem cell maintenance, confers resistance to chemotherapy and radiation, and serves as a significant prognostic marker and potential therapeutic target across numerous cancer types including breast, lung, and colorectal cancers.

Western Blot
Immunohistochemistry
IHC shows positive staining in paraffin-embedded human tonsil. Anti-BMI-1 antibody was used at 1/200 dilution, followed by a HRP Polymer for 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 colon. Anti-BMI-1 antibody was used at 1/200 dilution, followed by a HRP Polymer for 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 colon cancer. Anti-BMI-1 antibody was used at 1/200 dilution, followed by a HRP Polymer for 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 lung adenocarcinoma. Anti-BMI-1 antibody was used at 1/200 dilution, followed by a HRP Polymer for 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.
Immunocytochemistry
ICC shows positive staining in HeLa cells. Anti-BMI-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).
