Application Abreviews Notes
Flow Cyt Use 1µg for 106 cells. ab170192-Mouse monoclonal IgG2b, is suitable for use as an isotype control with this antibody.
WB Use a concentration of 1 - 5 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).
ELISA Use at an assay dependent concentration.


  • Function
    Ribonuclease inhibitor which inhibits RNASE1, RNASE2 and ANG. May play role in redox homeostasis.
  • Sequence similarities
    Contains 15 LRR (leucine-rich) repeats.
  • Domain
    The LRR domain forms a horseshoe-shaped structure that interacts tightly with target RNAses via a large protein interaction surface on its interior side.
  • Post-translational
    The N-terminus is blocked.
    At least 30 of the 32 cysteine residues are in the reduced form.

  • Overlay histogram showing A431 cells stained with ab77448 (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 (ab77448, 1µg/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 IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
