  • Target

    • Function
      Involved in the transfer of insoluble cholesteryl esters in the reverse transport of cholesterol.
    • Tissue specificity
      Expressed by the liver and secreted in plasma.
    • Involvement in disease
      Defects in CETP are a cause of hyperalphalipoproteinemia (HYPALIP) [MIM:143470]. Affected individuals show high levels of alpha-lipoprotein (high density lipoprotein/HDL).
      Defects in CETP are the cause of cholesteryl ester transfer protein deficiency (CETP deficiency) [MIM:607322]. This is an autosomal dominant condition associated with increased HDL cholesterol levels.
    • Sequence similarities
      Belongs to the BPI/LBP/Plunc superfamily. BPI/LBP family.
    • Cellular localization
      Secreted > extracellular space.
    • Information by UniProt

    • Anti-CETP antibody (ab19012)
      Predicted band size: 70 kDa

      Western blot analysis of CETP expresion in rabbit liver tissue lysate.
    • ICC/IF image of ab19012 stained HeLa cells. The cells were 4% PFA fixed (10mins) 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 (ab19012, 5µg/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.

    Customer reviews and Q&As

    Thank you very much for forwarding your Western blot image. The first three samples make a lot of sense to me. The protein is secreted, so I would expect to see much more protein present in serum than in cell or tissue lysates. As I said before, i...

    Thank you for your enquiry regarding ab19012 and your interest in our products. There are controversial data regarding whether mouse and rat have the CETP activity or proteins. We have used the mouse intestine and rat kidney, both of which show the ...

    Thank you for your enquiry. Ab19012 was indeed tested using rabbit liver tissue lysate, and a PVDF membrane was used. The lysate was prepared by directly sonicating the tissue pieces in SDS-PAGE sample buffer. 12% gel was used and 30 ug protein was loa...
