  • FunctionIFN-induced antiviral protein that mediates cellular innate immunity to at least three major human pathogens, namely influenza A H1N1 virus, West Nile virus (WNV), and dengue virus (WNV), by inhibiting the early step(s) of replication.
  • Sequence similaritiesBelongs to the CD225 family.
  • Post-translational
    Palmitoylation on membrane-proximal cysteines controls clustering in membrane compartments and antiviral activity against influenza virus.

  • IHC showing localisation of Fragilis (red) in cryosections of male genital ridges of E12.5 mouse embryos. Germ cells can be identified by staining with anti-Oct4 (green).

    ab15592 (anti-Fragilis) = red
    Oct4 = green
    DAPI (DNA) = blue

    The dilution of ab15592 used was 10 ug/ml.

  • Anti-Fragilis antibody, ab15592, recognised a small proportion of cells in a culture of human embryonic stem cells differentiated into a heterogenous mix of cells. Based upon the sequence of the immunogen used to generate this antibody the protein it recognizes is likely to be IFITM2 and/or IFITM3.
  • Fragilis - Primordial Germ Cell Marker was immunoprecipitated using 0.5mg E14Tg2a whole cell extract, 5µg of Rabbit polyclonal to Fragilis and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, E14Tg2a whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab15592.
    Secondary: Clean blot (HRP conjugate) at 1/1000 dilution.
    Band: 13kDa: Fragilis - Primordial Germ Cell Marker.

Thank you for your enquiry. I have looked at the amino acid sequence used to generate the antibody and can confirm it is at the N terminus of the protein, however the SwissProt reference we currently have (Q9D8L6) does not specify which part of the pro...
