Data Examples
Immunocytochemistry | STAT1 in HeLa Human Cell Line. STAT1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Rat Anti-Human STAT1 Monoclonal Antibody (Catalog # MAB1490) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # ) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for . |

Background: STAT1
STAT1 is a member of the STAT family of cytoplasmic transcription factors that mediate cytokine, growth factor and hormone receptor signal transduction. STAT1 is associated with type I and II interferon signaling. Phosphorylation of STAT1a at Y701 leads to dimerization and translocation to the nucleus to activate gene transcription. Human STAT1 shows 93% and 94% aa identity with mouse and rat STAT1, respectively, over the region used as an immunogen. This region is identical between isoforms STAT1a (91 kDa) and STAT1b (84 kDa).
