Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB 1/2000 - 1/10000. Detects a band of approximately 145 kDa (predicted molecular weight: 119 kDa).
IP Use at 2-5 µg/mg of lysate.


  • Function

    Recognizes and hydrolyzes the peptide bond at the C-terminal Gly of ubiquitin. Involved in the processing of poly-ubiquitin precursors as well as that of ubiquinated proteins. May be involved in the regulation of NF-kappa-B activation by TNF receptor superfamily via its interactions with RELA and TRAF2. May also play a regulatory role at post-synaptic sites.
  • Tissue specificity

    Widely expressed.
  • Sequence similarities

    Belongs to the peptidase C19 family.
    Contains 3 DUSP domains.
    Contains 1 ubiquitin-like domain.
  • Cellular localization

    Cytoplasm. Nucleus.

    Exposure time: 3 seconds
  • Detection of USP48 by Western Blot of Immunprecipitate.
    ab72226 at 1µg/ml staining USP48 in HeLa whole cell lysate immunoprecipitated using ab72226 at 3µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
    Detection: Chemiluminescence with exposure time of 1 second.
  • ICC/IF image of ab72226 stained HeLa cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab72226, 5µg/ml) overnight at +4°C. The secondary antibody (green) was for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
