  • General notes

    Abcam is committed to meeting high standards of ethical manufacturing and has decided to discontinue this product by June 2019 as it has been generated by the ascites method. We are sorry for any inconvenience this may cause. We would recommend antibody ab123574 as a replacement.



Our Abpromise guarantee covers the use of ab56820 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 - 5 µg/ml. Predicted molecular weight: 51 kDa.
IHC-P Use a concentration of 3 µg/ml.
ICC/IF Use at an assay dependent concentration. PubMed: 21169636


  • Function
    May be a crucial component of the cytoskeleton of highly motile cells, functioning both in the invagination of large pieces of plasma membrane, as well as in forming protrusions of the plasma membrane involved in cell locomotion. In mycobacteria-infected cells, its retention on the phagosomal membrane prevents fusion between phagosomes and lysosomes.
  • Tissue specificity
    Expressed in brain, thymus, spleen, bone marrow and lymph node. Low in lung and gut.
  • Sequence similarities
    Belongs to the WD repeat coronin family.
    Contains 7 WD repeats.
  • Cellular localization
    Cytoplasm > cytoskeleton. Cytoplasm > cell cortex. Cytoplasmic vesicle > phagosome membrane. In non-infected macrophages, associated with the cortical microtubule network. In mycobacteria-infected macrophages, becomes progressively relocalized and retained around the mycobacterial phagosomes. Retention on the phagosomal membrane is strictly dependent on mycobacterial viability and not due to impaired acidification.

  • ab56820 staining Coronin 1a in HL-60 cells by Immunocytochemistry/ Immunofluorescence.
    The cells were washed three times with PBS after the phagocytosis assay and fixed with 3.3% paraformaldehyde for 15 minutes. Cells were washed twice with PBS containing 1 mm MgCl2 and 0.1% BSA (staining buffer), permeabilized with 0.2% Triton X-100 in staining buffer for 3 minutes, and blocked with PBS containing 1 mm MgCl2 and 5% BSA for 30 minutes. To assess the distribution of Coronin 1a, a phagocytosis assay was started as described above, and the cells were treated with C3bi-zymosan for 10 minutes at 37 °C. After washing twice to remove unbound C3bi-zymosan particles, the treated cells were reincubated for the indicated times at 37 °C and then fixed and permeabilized. Cells were incubated with ab56820 for 1 hour and then with an Alexa Fluor 488-conjugated phalloidin. For more details please see journal article.
