  • Relevance
    RAI1 (retinoid-acid induced protein 1) may be involved in neuronal differentiation. RAI1 is highly similar to its mouse counterpart and is expressed at high levels mainly in neuronal tissues. RAI1 has a polymorphic polyglutamine tract in it's N-terminal domain. Expression of the mouse counterpart in neurons is induced by retinoic acid. The RAI1 gene is associated with both the severity of the phenotype and the response to medication in schizophrenic patients. Defects in RAI1 are a cause of Smith-Magenis syndrome (SMS). There are four named isoforms.
  • Cellular localization
    Cytoplasmic and Nuclear. In neurons it is localized to neurites.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian carcinoma tissue labelling RAI1 with ab86599 at 1/1000 (1µg/ml). Detection: DAB.
  • ICC/IF image of ab86599 stained HeLa cells. The cells were 100% methanol fixed (5 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 ab86599 at 5µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

  • All lanes : Anti-RAI1 antibody (ab86599) at 0.1 µg/ml

    Lane 1 : Whole cell lysate from HeLa cells at 50 µg
    Lane 2 : Whole cell lysate from HeLa cells at 15 µg
    Lane 3 : Whole cell lysate from HeLa cells at 5 µg

    Developed using the ECL technique.

    Predicted band size: 203 kDa
    Observed band size: 280 kDa (why is the actual band size different from the predicted?)

    Exposure time: 3 minutes
  • Western Blot detection of RAI1 in Immunoprecipitates of Whole cell lysate of HeLa cells (1 mg for IP, 20% of IP loaded) using ab86599 at 10 µg/mg lysate for IP and at 1 µg/ml for subsequent Western blot detection. Lane 2 represents control IgG IP.
    Detection: Chemiluminescence with an exposure time of 30 seconds.
