Application Abreviews Notes
IHC-Fr Use at an assay dependent concentration.
WB 1/500 - 1/1000. Predicted molecular weight: 359 kDa.
IHC-P 1/500 - 1/1000. Antigen retrieval is recommended.
Flow Cyt 1/100 - 1/550. Ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
ICC/IF 1/250 - 1/500.
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionThought to be required for maintaining cell proliferation.
    • Sequence similaritiesContains 1 FHA domain.
    • Developmental stageExpression of this antigen occurs preferentially during late G1, S, G2 and M phases of the cell cycle, while in cells in G0 phase the antigen cannot be detected.
    • Cellular localizationNucleus. Nucleus, nucleolus. Chromosome. Predominantly localized in the G1 phase in the perinucleolar region, in the later phases it is also detected throughout the nuclear interior, being predominantly localized in the nuclear matrix. In mitosis, it is present on all chromosomes.

    • Overlay histogram showing Ramos cells stained with ab92742 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab92742, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Tissue was fixed with paraformaldehyde, permeabilized and blocked with 4% serum + 1% BSA for 30 minutes at 22°C. Samples were incubated with primary antibody (1/500 in blocking buffer) for 18 hours at 4°C. An Alexa Fluor® 568-conjugated donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody. Magnification: 20X. Counterstained with DAPI.

    ab92742 has indeed been tested in western blot on mouse and rat samples and gave a negative result.

    Merci pour votre réponse.

    Il n'y à aucun problème. Envoyez nous les images quand vous êtes de retour au laboratoire.

    Je vous souhaite un bon été et je me réjouis d'avoir de vos nouvelles.

    J'ai reçu confirmation du laboratoire que l'anticorps avait été testé sur des cellules du cerveau, du cœur, des reins et de la rate de la souris (et rat) et ne donnait aucun signal. Le laboratoire n'avait pas test&eacu...
