靶标

  • 功能Activates insulin, somatostatin, glucokinase, islet amyloid polypeptide and glucose transporter type 2 gene transcription. Particularly involved in glucose-dependent regulation of insulin gene transcription. Binds preferentially the DNA motif 5'-[CT]TAAT[TG]-3'. During development, specifies the early pancreatic epithelium, permitting its proliferation, branching and subsequent differentiation. At adult stage, required for maintaining the hormone-producing phenotype of the beta-cell.
  • 组织特异性Duodenum and pancreas (Langerhans islet beta cells and small subsets of endocrine non-beta-cells, at low levels in acinar cells).
  • 疾病相关Defects in PDX1 are a cause of pancreatic agenesis (PAC) [MIM:260370]. This autosomal recessive disorder is characterized by absence or hypoplasia of pancreas, leading to early-onset insulin-dependent diabetes mellitus. This was found in a frameshift mutation that produces a truncated protein and results in a second initiation that produces a second protein that act as a dominant negative mutant.
    Defects in PDX1 are a cause of non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853]; also known as diabetes mellitus type 2. NIDDM is characterized by an autosomal dominant mode of inheritance, onset during adulthood and insulin resistance.
    Defects in PDX1 are the cause of maturity-onset diabetes of the young type 4 (MODY4) [MIM:606392]; also symbolized MODY-4. MODY is a form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease.
  • 序列相似性Belongs to the Antp homeobox family. IPF1/XlHbox-8 subfamily.
    Contains 1 homeobox DNA-binding domain.
  • 结构域The Antp-type hexapeptide mediates heterodimerization with PBX on a regulatory element of the somatostatin promoter.
    The homeodomain, which contains the nuclear localization signal, not only mediates DNA-binding, but also acts as a protein-protein interaction domain for TCF3(E47), NEUROD1 and HMG-I(Y).

Anti-PDX1 antibody 图像

  • Immunostaining of islets from 4 week-old mice with ab47308 guinea pig anti-PDX1 (red) and an anti-insulin antibody (green).
  • Immunohistochemical analysis of developing murine pancreas taken from wild-type (+/+) and SEL1L-null mice (-/-). PDX1 (green) was stained with ab47308.

    Tissue was fixed with paraformaldehyde before freezing and sectioning. Sections were permeabilized with 0.2% Triton X-100 for 20 min and blocked with 5% normal donkey serum and 1% BSA in PBS at room temperature for at least 1 hour. Samples were incubated with primary antibody (1/100 in 1% BSA in PBS) overnight at 4°C. A Cy2®-conjugated donkey anti-guinea pig IgG (1/500) was used as the secondary antibody.

Thank you for contacting us.

PDX1 will be expressed in the nucleus ofpancreatic islet and intercalated duct cellsin adult mice. I hope this helps, please let me know if you need any additional information.

I have issued a free of charge replacement with the order number ****. This is for rabbit anti-PDX1, ab47267, to replace ab47308. The fixation is with 4% PFA for 5 minutes, followed by permeabilization with Triton X-100. The full protocol is below...

I assume you have the antibody ab47267, as that is the only rabbit anti-PDX1 in our catalogue that has been tested for ICC. We do not have samples of any of our antibodies but I can send a full vial as a replacement, perhaps from a lot different from w...

I am sorry to read that this is still not working for you. My guess is that the fixation is still too long at 2 hours, even with 4% vs. 10% PFA, or that there is lot-to-lot variability with regards to compatibility with formaldeyhe-based fixation. ...

Following up my previous message, the laboratory and I think the problem may be the 10% PFA fixation for 10 minutes at room temperature. The lab used 4% PFA and fixed for 2 hours at 4C. I think the fixation time could be made shorter than two ho...
