Our Abpromise guarantee covers the use of ab21032 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
Sandwich ELISA Use at an assay dependent concentration. PubMed: 21371998
ICC/IF Use a concentration of 5 µg/ml.
ELISA 1/5000 - 1/40000. Can be paired for ELISA with Goat polyclonal to Apolipoprotein CIII (Biotin) (ab21024).
WB Use at an assay dependent dilution. Predicted molecular weight: 11 kDa.


  • Function
    Inhibits lipoprotein lipase and hepatic lipase and decreases the uptake of lymph chylomicrons by hepatic cells. This suggests that it delays the catabolism of triglyceride-rich particles.
  • Tissue specificity
    Constitutes 50% of the protein fraction of VLDL and 2% of that of HDL. Synthesized predominantly in liver and to a lesser degree in intestine.
  • Involvement in disease
    Defects in APOC3 may be a cause of hyperalphalipoproteinemia (HYPALIP) [MIM:143470]. Affected individuals show high levels of alpha-lipoprotein (high density lipoprotein/HDL).
  • Sequence similarities
    Belongs to the apolipoprotein C3 family.
  • Post-translational
    O-linked glycan consists of Gal-GalNAc disaccharide, further modified with up to 3 sialic acid residues. O-glycosylated on Thr-94 with a core 1 or possibly core 8 glycan.

  • Sandwich ELISA, detecting Apolipoprotein CIII levels in human or cynomolgus monkey serum, using ab21032 as capture antibody.

    Anti-human Apolipoprotein CIII polyclonal antibody (ab21032 at 10 µg/ml) was added to an ELISA plate and incubated overnight at 4°C. Blocking buffer was added and incubated for 1 hour at room temperature. 50 µl of serum or standard was added to each well and incubated for 2 hours at room temperature. After washing, 50 µl/well of detection antibody (ab21024) was added and incubated at room temperature 1 hour followed by 50 µl/well of Streptavidin-HRP (ab64269). After color development, the absorbance was read at 450nm.

  • All lanes : Anti-Apolipoprotein CIII antibody (ab21032) at 1 µg/ml

    Lane 1 : Native Human Apolipoprotein CIII (ab77944) at 0.1 µg
    Lane 2 : Native Human Apolipoprotein CIII (ab77944) at 0.01 µg

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 11 kDa

    Exposure time: 1 minute
  • ICC/IF image of ab21032 stained HepG2 (Human liver hepatocellular carcinoma cell line) cells.

    The cells were fixed in 4% formaldehyde for 10 minutes and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab21032, 5 µg/ml) 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 1 hour. Alexa-Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1 hour.

    DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 µM.
