Scientific Data

Western Blot Detection of Human c-Fos antibody by Western Blot. View Larger

Detection of Human c-Fos by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 200 nM PMA for 4 hours. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human c-Fos Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7254) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for c-Fos at approximately 62 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

c‑Fos in HeLa Human Cell Line. c-Fos was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human c-Fos Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7254) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: c-Fos

Cellular oncogene fos (c-Fos) is one of four Fos family proteins that associate with Jun family proteins to form the AP-1 transcription factor complex. It is thought to have an important role in signal transduction, cell proliferation and differentiation. Cellular oncogene fos (c-Fos) is constitutively sumoylated by SUMO1, SUMO2 and SUMO3. Within aa 1-132, human c-Fos shares 92% aa sequence identity with mouse and rat c-Fos.
