Data Examples

Detection of Human PDX‑1/IPF1 by Western Blot. Western blot shows lysates of beta TC‑6 mouse beta cell insulinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human PDX‑1/IPF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2419) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for PDX‑1/IPF1 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Detection of Mouse PDX‑1/IPF1 by Simple WesternTM. Simple Western lane view shows lysates of beta TC‑6 mouse beta cell insulinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for PDX‑1/IPF1 at approximately 48 kDa (as indicated) using 10 µg/mL of Goat Anti-Human PDX‑1/IPF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2419) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the
12-230 kDa separation system.

Immunocytochemistry

PDX‑1/IPF1 in BG01V Human Embryonic Stem Cells. PDX‑1/IPF1 was detected in immersion fixed BG01V human embryonic stem cells differentiated into pancreatic progenitor cells using Goat Anti-Human PDX‑1/IPF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2419) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 493-conjugated Anti-Goat IgG Secondary Antibody (green; Catalog # NL003) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Immunohistochemistry

PDX‑1/IPF1 in Human Pancreatic Cancer Tissue. PDX‑1/IPF1 was detected in immersion fixed paraffin-embedded sections of human pancreatic cancer tissue using Goat Anti-Human
PDX‑1/IPF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2419) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to nuclei in cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: PDX-1/IPF1
PDX-1, also known as islet/duodenum homeobox-1 (IDX-1), is a homeodomain-containing transcription factor. During embryonic development, PDX-1 is required for pancreas differentiation in adult islet cells. PDX-1 regulates beta -cell specific gene expression and function. Human and mouse PDX-1 share 88% amino acid sequence homology.
