    Abcam is committed to meeting high standards of ethical manufacturing and has decided to discontinue this product by June 2019 as it has been generated by the ascites method. We are sorry for any inconvenience this may cause. 



Our Abpromise guarantee covers the use of ab13649 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ChIP Use 1µg for 106 cells.
Flow Cyt Use 1-2µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
IHC-P Use a concentration of 5 µg/ml.
IHC-Fr Use at an assay dependent concentration.
WB Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 73 kDa (predicted molecular weight: 73 kDa).
ICC/IF Use at an assay dependent concentration.


  • 相关性
    Even though the tumor suppressor gene p53 is highly important in human cancer, as indicated by the fact that it is mutated in about 50% of cases, up to a few years ago no similar proteins had been identified. Two p53 homologues are now identified, p73 and p63, with high amino acid identity suggesting similar functions. Both p63 and p73 have two significant structural peculiarities compared with p53; the presence of an extended non-conserved C-terminus containing a sterile alpha motive (SAM), (typical of developmental proteins), and the presence of number of different splicing isoforms differing in the N-terminus or in the absence of the transactivation domain (delta N forms).

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human lung squamous cell carcinoma tissue labelling p73 Delta N with ab13649 at 5µg/ml. Staining was enhanced by boiling tissue sections in 10mM sodium citrate buffer, pH6.0 for 10-20 minutes followed by cooling at room temperature for 20 minutes.

  • IHC analysis of p73 Delta N in embryonic day 15 (A) and day 17 (B) E15 rat embryonic kidney at 1:2000. p73 Delta N is expressed in ureteric bud (UB) branches, and metanephrogenic mesenchyme (MM), as well as in cells invading the glomerular cleft. p73 Delta N is expressed in the ureteric bud (UB) branches, metanephrogenic mesenchyme (MM), and nephron progenitors.
  • Overlay histogram showing HeLa cells stained with ab13649 (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. The cells were then incubated with the antibody (ab13649, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed.
