Prox1 Antibody [Unconjugated]

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Prox1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2727) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Prox1 at approximately 83 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Prox1 was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Goat Anti-Human Prox1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2727) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (left panel, red; Catalog # NL001) and counterstained with DAPI (right panel, blue). Specific staining was localized to nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Prox1 at approximately 114 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Prox1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2727) 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.

Background

Prox1, the homologue of Drosophila Prospero, is a homeobox-containing transcription factor that binds and functions as a co-receptor of liver receptor homolog 1 (LRH1/NR5A2). It is a specific marker for lymphatic endothelial cells as well as hepatoblasts and hepatocytes. Human Prox1 shares 97% amino acid sequence homology with mouse and rat Prox1.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
