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

Application Abreviews Notes
IHC-Fr 1/300. PubMed: 17021035
WB 1/5000. Predicted molecular weight: 50-55 kDa. This dilution was sufficient for detection of Cytochrome P450 in 20ug of human liver microsomes by colorimetric immunoblot analysis using Goat anti-Rabbit IgG:AP as the secondary antibody.
ICC/IF 1/1000.
IHC-P Use at an assay dependent concentration. PubMed: 24155903


  • Function
    Metabolizes several precarcinogens, drugs, and solvents to reactive metabolites. Inactivates a number of drugs and xenobiotics and also bioactivates many xenobiotic substrates to their hepatotoxic or carcinogenic forms.
  • Sequence similarities
    Belongs to the cytochrome P450 family.
  • Cellular localization
    Endoplasmic reticulum membrane. Microsome membrane.

  • ab28146 staining cells of rat liver sections by IHC-Fr.  Cells were fixed in acetone and blocked with 1% BSA for 5 minutes at 25°C prior to incubating with ab28146 diluted 1/300 for 30 minutes at 25°C.  An Alexa Fluor® 594 conjugated goat anti-rabbit antibody was used as the secondary.

    Double IF labeling with CYP2E1 (Red) and dipeptidyl peptidase IV (Green)

  • ICC/IF image of ab28146 stained HeLa cells. The cells were 4% PFA 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 (ab28146, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 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.
