Intracellular Staining by Flow Cytometry Detection of FoxJ1 antibody in HEK293 Human Cell Line antibody by Flow Cytometry. View Larger

Detection of FoxJ1 in HEK293 Human Cell Line by Flow Cytometry. HEK293 human embryonic kidney cell line was stained with Rat Anti-Human FoxJ1 Monoclonal Antibody (Catalog # MAB3619, filled histogram) or isotype control antibody (Catalog # MAB0061, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: FoxJ1

Human FoxJ1 (also HNF-4) is a 45 kDa, class 1 member of the HNF-3/fork-head gene family of transcription factors. It is 421 amino acids (aa) in length and contains one fork-head DNA binding domain (aa 120‑210). The presence of basic residues in the fork-head domain makes FoxJ1 a class 1 Fox protein. FoxJ1 induces cilia in lung and oviduct and maintains T cell tolerance to self-antigens. It is known to modulate NF kappa B activity. Over the range of amino acids used for immunization, human FoxJ1 is 89% aa identical to dog FoxJ1 and 87% aa identical to both mouse and rat FoxJ1.
