Applications

Our Abpromise guarantee covers the use of ab122969 in the following tested applications.

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

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 120 kDa (predicted molecular weight: 78 kDa).
IHC-P 1/8000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF Use a concentration of 5 µg/ml.

Target

  • FunctionEssential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). It probably represents a stabilizing cofactor required for the assembly of the gamma-secretase complex.
  • Tissue specificityWidely expressed.
  • Sequence similaritiesBelongs to the nicastrin family.
  • Cellular localizationMembrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 78 kDa
    Observed band size : 120 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 75 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds
  • ICC/IF image of ab122969 stained Mouse Embryonic Stem 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 ab122969 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution 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.

  • ab122969 staining Nicastrin in Human breast carcinoma tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% BSA for 10 minutes at 21°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/8000 in TBS/BSA/azide) for 16 hours at 21°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/250) was used as the secondary antibody.
