  • 功能
    Transcription factor for the thyroid-specific expression of the genes exclusively expressed in the thyroid cell type, maintaining the functional differentiation of such cells.
  • 组织特异性
    Expressed in the excretory system, thyroid gland and Wilms tumors.
  • 疾病相关
    Defects in PAX8 are the cause of congenital hypothyroidism non-goitrous type 2 (CHNG2) [MIM:218700]. CHNG2 is a disease characterized by thyroid dysgenesis, the most frequent cause of congenital hypothyroidism, accounting for 85% of case. The thyroid gland can be completely absent (athyreosis), ectopically located and/or severely hypoplastic. Ectopic thyroid gland is the most frequent malformation, with thyroid tissue being found most often at the base of the tongue.
  • 序列相似性
    Contains 1 paired domain.
  • 发展阶段
    In developing excretory system, during thyroid differentiation and in adult thyroid.

  • Anti-PAX8 antibody [PAX8R1] (ab53490) at 1/100 dilution + HeLa whole cell lysate at 50 µg

    Mouse IgG antibody at 1/2500 dilution

    Predicted band size : 48 kDa
    Observed band size : 60 kDa (why is the actual band size different from the predicted?)
  • ab53490 staining PAX8 in Mouse thyroid tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with 0.1% Tween 20 and blocked with 10% serum for 30 minutes at 24°C. Samples were incubated with primary antibody (1/20 in 10% goat serum in PBS) for 1 hour at 24°C. An Alexa Fluor® 488-conjugated Goat anti-mouse IgG polyclonal (1/500) was used as the secondary antibody.

  • IHC image of ab53490 staining in human kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab53490, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • HeLa cells were fixed in 2% paraformaldehyde/PBS and then permeabilized in 90% methanol. Cells were stained with ab53490 at 0.5 µg/sample (shaded) or isotype control (unshaded) followed by Alexa Fluor® 488-conjugated goat anti-mouse IgG (0.25µg)

  • ab53490, at a 1/10 dilution, staining PAX8 in HeLa cells, using Immunocytochemistry, plus AlexaFluor®488 Goat Anti-mouse IgG secondary anitbody.
  • Immunoprecipitation: ab53490: 5µg, RIPA lysate of HeLa cells: 500µg. WB: ab53490 at a 1:100 dilution, Secondary antibody - anti-mouse IgG at a 1:1000 dilution

Thank you for contacting us.

I am sorry to hear that you are also experiencing problems with this antibody (additionally to the Anti-TTF1 antibody [8G7G3/1] (ab72876) ). Could you please fill in the questionnaire for both products and send the...

Thank you for contacting us. Although we have indicated Pax8 to be located in the nucleus, the literature shows Pax8 expression can be nuclear as well as cytoplasmic. I apologize for the confusion.

I hope this information is helpful to you. Pl...

Thank you for your patience.

I have heard back from the lab with the following information:

We have not done anytesting in regards to cross reactivity of ab53490 with PAX2 and PAX5 on endogenous protein. Also, we haven't done any e...

Thank you for contacting us.

The immunogen is a recombinant C-terminal fragment corresponding to Human PAX8,based on theamino acid range 318-426 aa. The exact epitope has not been mapped, therefore we do not know where the antibody would bin...

I'm happy to help! Best of luck with your experiment.

I have used these columns but not for an application as sensitive as the one you describe.For my purposes it had been sufficient to have perhaps 95% or more of protein that should flow through will flow through and about the same percentage of protein ...

Thank you for your enquiry.

We only have the one formulation of ab53490, which contains 1% BSA. We can often create a custom batch with customer buffer formulations but this would require a bulk order, which would be 10 vials of antibody. Read More

Thank you for contacting us. I am sorry that ab53490 has given no signal on your customer's samples. Since the PAX8 antigen is expressed in the nucleus, adding a brief permeabilization step may help to increase the signal. I would recommend using 0.1...
