Our Abpromise guarantee covers the use of ab845 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
Flow Cyt 1/4.
IHC-P Use at an assay dependent concentration.
Proteolytic treatment is required prior to immunostaining of formalin fixed paraffin embedded tissue sections. High temperature antigen unmasking may improve the staining.
IHC-Fr Use at an assay dependent concentration. Acetone fixed.
ICC/IF Use at an assay dependent concentration.


  • FunctionCould play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.
  • Tissue specificityHighly expressed by blood monocytes and tissue macrophages. Also expressed in lymphocytes, fibroblasts and endothelial cells. Expressed in many tumor cell lines which could allow them to attach to selectins on vascular endothelium, facilitating their dissemination to secondary sites.
  • Sequence similaritiesBelongs to the LAMP family.
  • Post-translational
    N- and O-glycosylated.
  • Cellular localizationCell membrane and Endosome membrane. Lysosome membrane.

Anti-CD68 antibody [KP1], prediluted images

  • Overlay histogram showing THP1 cells stained with ab845 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab845, 1/4 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
