Our Abpromise guarantee covers the use of ab80906 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
WB Use a concentration of 1 µg/ml. Detects a band of approximately 160 kDa (predicted molecular weight: 198 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA 1/12500.
ICC/IF Use a concentration of 1 µg/ml.


  • Function
    Has a DNA polymerase activity on nicked double-stranded DNA and on a singly primed DNA template. The enzyme activity is resistant to aphidicolin, and inhibited by dideoxynucleotides. Exhibites a single-stranded DNA-dependent ATPase activity. Could be involved in the repair of interstrand cross-links.
  • Tissue specificity
    Highly expressed in testis.
  • Sequence similarities
    Belongs to the DNA polymerase type-A family.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.

  • Anti-DNA Polymerase theta antibody (ab80906) at 1 µg/ml + placenta lysate at 10 µg

    HRP conjugated anti-Rabbit IgG at 1/50000 dilution

    Predicted band size : 198 kDa
    Observed band size : 160 kDa (why is the actual band size different from the predicted?)
  • ICC/IF image of ab80906 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 (ab80906, 1µg/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.
