Application Abreviews Notes
Flow Cyt 1/10 - 1/50.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.

WB 1/50 - 1/100. Predicted molecular weight: 70 kDa.
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

  • Function
    Beta-oxidation of fatty acids. The highest activity concerns the C6 to C10 chain length substrate. Converts the end product of pristanic acid beta oxidation, 4,8-dimethylnonanoyl-CoA, to its corresponding carnitine ester.
  • Pathway
    Lipid metabolism; fatty acid beta-oxidation.
  • Sequence similarities
    Belongs to the carnitine/choline acetyltransferase family.
  • Cellular localization

  • ICC/IF image of ab103448 stained T24/83 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 ab103448 at 5 µg/mL overnight at +4°C. The secondary antibody (green) was DyLight® 488 Goat anti-Rabbit IgG (H+L) (ab96899) 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.

  • ab103448, at a 1/50 dilution, staining CROT/COT in formalin fixed and paraffin embedded Human brain tissue which was peroxidase conjugated to the secondary antibody, followed by DAB staining.

  • Flow cytometric analysis of K562 cells with ab103448 at a 1/10 dilution (bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.
