  • Relevance

    Luciferase from the firefly has become one of the more widely used reporter proteins for the study of gene expression. Luciferase catalyzes a bioluminescent reaction which requires the substrate luciferin as well as Mg2+ and ATP. Mixing these reagents with the cell extract containing luciferase, results in a flash of light that decays rapidly. This light can be detected by a luminometer. The total light emission is proportional to the luciferase activity of the sample.

  • ab21176 at 10 µg/mL staining Luciferase in transfected HEK-293 (Human epithelial cell line from embryonic kidney) cells by ICC/IF.

    The cells were fixed with methanol and acetone. An FITC conjugated anti-Rabbit IgG was used as the secondary antibody. 

    Left panel: Un-transfected cells.

    Right panel: Transfected cells.

  • ab21176 at 1/200 dilution staining engineered adult rat stromal stem cells by ICC/IF.

    The cells were fixed in 2% paraformaldehyde and 0.1% Triton X-100 was used for cell permeabilization (15 minutes incubation time). The cells were incubated with the antibody overnight at 4°C. The image shows Luciferase (green-upper right panel), counterstained cell nuclei (DAPI-blue-upper left panel), overlay (lower left panel) and a phase contrast image (lower right panel).

    The image was taken with a confocal laser scanning microscope equipped with an additional laser differential Interference Contrast (DIC) mode.

  • ab21176 staining Firefly Luciferase in mouse cerebellum tissue sections by Immunohistochemistry (IHC-Fr - frozen sections).

    Tissue was fixed with acetone, permeabilized with PBS + 0.1% Triton X-100 (PBST) for 10 minutes and blocked with 10% serum for 1 hour at 22°C. Samples were incubated with primary antibody (1/1500 in 10% goat serum in PBST) for 1 hour at 22°C. An Alexa Fluor® 555-conjugated Goat anti-rabbit IgG polyclonal (1/1000) was used as the secondary antibody.

  • Immunocytochemical analysis analysis of HEK-293T (Human epithelial cell line from embryonic kidney transformed with large T antigen) cells overexpressing luciferase labeling Luciferase with ab21176 at a concentration of 10 μg/mL. The secondary antibody was a Goat anti-Rabbit IgG, FITC conjugate.

  • ab21176 staining mouse mammary carcinoma cells by ICC/IF.

    Cells were PFA fixed and permeabilized in 0.1% Triton X-100 prior to blocking with a commercial blocking agent. The primary antibody was diluted 1/100 and incubated with the sample for 1 hour at 25°C. An Alexa-Fluor® 555 conjugated goat anti-rabbit antibody was used as the secondary.

    The image shows firefly luciferase (red) in mouse tumour cells and cell nuclei counterstained with Hoechst (blue).

Thank you for your inquiry.

I heard back from the testing lab that they did not have any cell staining data for ab21176 with untransfected cells.

I can point you to our references section of the online datasheet as you may be able to find one in a publication:


I hope this information helps. Please contact us with any other questions.

Thank you for contacting Abcam regarding ab21176.

I am sorry that you were experiencing difficulties with this antibody in IHC. If you believe this is due to the antibody being defective, I am happy to provide additional technical assistance with troubleshooting or a credit, as this product is guaranteed for IF under our Abpromise. Please provide some additional protocol information.

Regarding using the antibody in WB, we are not sure if this antibody will be suitable for western, but would recommend a starting dilution of 1 ug/ml.

I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions or concerns.

Thank you for your enquiry.

Here is an example of a secondary antibody you can use to detect ab64569:


ab98712 is conjugated to a fluor that can be visualized with the same filter set as is used for FITC. This antibody has been preadsorbed to rat serum (among others) and has shown minimum cross reactivity to rat immunoglobulins.

We have a couple useful tools on our website for selecting secondary antibodies. One is a search and another is a browse feature and both can be found at:

I hope this is helpful. Please contact me again if you have any further questions.
