Application Abreviews Notes
ICC/IF Use a concentration of 10 µg/ml.

WB 1/100 - 1/500. Predicted molecular weight: 45 kDa.


  • FunctionMajor transport protein for glucocorticoids and progestins in the blood of almost all vertebrate species.
  • Tissue specificityPlasma; synthesized in liver. Has also been identified in a number of glycocorticoid responsive cells.
  • Involvement in diseaseDefects in SERPINA6 are a cause of corticosteroid-binding globulin deficiency (CBG deficiency) [MIM:611489]. CBG deficiency is an extremely rare hereditary disorder characterized by reduced corticosteroid-binding capacity with normal or low plasma corticosteroid-binding globulin concentration, and normal or low basal cortisol levels associated with hypo/hypertension and muscle fatigue.
  • Sequence similaritiesBelongs to the serpin family.
  • Post-translational
    N-glycosylated; binds 5 oligosaccharide chains.
    Glycosylation in position Asn-260 is needed for steroid binding.
  • Cellular localizationSecreted.

Anti-Cortisol Binding Globulin antibody images

  • ICC/IF image of ab107368 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab107368, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Predicted band size : 45 kDa
  • IHC image of ab107368 staining in human liver formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab107368, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
